You stuck a hyphen in the last command. Best to just copy/paste what I wrote.
EDIT: Actually the last 2.
EDIT2 - My bad. Filename appears correct. Back to the drawing board...

That's the name of the file, though, as it arrives from the XDA link. the twrp site insists they have no such file for the v20 as it is.
Tried renaming the file to just twrp.img, and then I get this:

Ya, just reread and agree. I'll look in a bit (time permitting) and go back to edit my reply - sorry. Crazy house today....
EDIT: Are you 100% sure the bootloader is unlocked?

I understand. it's been crazy busy for me. Hence why it took so long for me to actually try this.

OK. I *think I found it (damn brain farts). Try:
fastboot boot recovery recovery-twrp-us996-2018-10-18.img
Pretty sure I missed an argument:
fastboot boot recovery <image-name>
EDIT: Nope, that ain't necessary. Should be the former. If I don't fall asleep after dinner, I'll regroup - sorry...

Ok, I got up to have a smoke and decided to plug in the actual phone. Note than I'm on Linux, but adb and fastboot terminal screens are the same regardless of native OS. I did try to boot the image:
fastboot boot <my-image-name> and encountered security error, so I decided to actually flash it:
fastboot flash <my-image-name> and it downloaded successfully.
fastboot reboot got me back to the phone's OS
Next:
==============================================================
[actual terminal input/output] (other than editing device serial for this posting)
curley@Z97N-WIFI /Phones/LG/V20-VS995 $ adb devices
List of devices attached
LGVS995c16xxxxx device
curley@Z97N-WIFI /Phones/LG/V20-VS995 $ adb reboot recovery
curley@Z97N-WIFI /Phones/LG/V20-VS995 $ adb devices
List of devices attached
LGVS995c16xxxxx recovery
curley@Z97N-WIFI /Phones/LG/V20-VS995 $
==============================================================
And I'm now in TWRP.
You should be as well. If so, flash Magisk and good to go from there.
Unsure what is different on your end, but I need to go back and edit/delete my earlier post about booting into TWRP from the computer terminal, as it doesn't work on this device. I think I know *why,* but the brain isn't 100% in gear. <deleted>
Bottom line, if the recovery flashed correctly, then "adb reboot recovery" should work. It does here...

Ah-hah! I should have read up on this before jumping in...
OK, scolding over <g>. You're still going to need to use a variant of Dirty Cow, and it's not nearly as easy as that POS link suggests. Check out a REAL thread here. Regarding the term recowvery over there: it's not a typo and is meant to define that particular exploit. Follow the very nice guide and you should be fine.
Good Luck...
This is utter bullsh*t and is your very problem! NEVER follow a "How To Root <whatever>" from some obscure site (skyneel.com - really?). Whoever would trust their device to such an undocumented piece of crap with ZERO feedback deserves a brick. You are very lucky. You aren't new here, so you should know better. Either ask right here, or go to XDA. Both forums have very talented and experienced participants. Did you see any "participants" @skyneel.com?

There was nothing I could find on XDA... as it is, I couldn't even find a compatible TWRP on the TWRP site.

There is no "official" TWRP, only some (actually pretty good) unofficial ones. Sorry to say, you're probably screwed anyway if you've taken any updates. This will only work on older firmware (pre-November 2016) I think. There may be a KDZ available you can flash, but anti-rollback might be of issue. "Uppercut" may help, but it can get deep. Time to do some serious reading there, Baba Looey.

How would I be able to tell what it's on? because I only did receive it this past weekend.

You might luck out, so DON"T take any updates just yet. Go to Settings/About Phone/Software info and you'll see "Android security patch level" with a date underneath. Best to research the actual "Software version," but the former is a pretty good indicator. Good luck.
EDIT: A very brief thread search (of the one I linked to on XDA) indicates this may not be an issue on the US996 after all. Better you search/read up on it yourself as I have a different model (VS995). Plenty of help there if you simply ask the question and provide your model/firmware version. Best to search first as always....

Just took another peek at the thread. While the exploit won't work on yours, the very 1st line in the OP states: "Note for US996: It's probably easier for you guys just to flash TWRP the normal way and pull your battery then do the factory reset dance to get in!" This tells me I am mistaken, however you will lose your data (to be expected anyway). If you've already flashed the recovery I linked you to earlier (post now deleted - sorry), shutdown the phone and do the button press thingy to get into recovery:
Power down, pull battery, replace.
Hold power + Vol down until you see the LG logo appear, then release Power briefly, and press/hold power again.
You'll see the "factory reset" screen when successful (may take some practice).
Select yes with the Vol down button, then power to confirm, and it will ask you again, so repeat.
You'll either boot into recovery (that you reported was successfully flashed) or you're back to stock.
Apologies for the "scolding," but I think it's that simple. What's to lose that you wouldn't otherwise? Should you succeed getting into TWRP, go ahead and flash Magisk as this could help with "adb reboot recovery." Atleast you'll be able to use the "Simple Reboot" app.
I'm thinking you are lucky - I would go for it!

I don't have this particular model. Something isn't setup correctly or it's unique to the US996. I'd suggest asking in the forum for your model.
EDIT: I did find the 10f (rootable) KDZ here in case you brick. You can use LGUP combined with Uppercut to restore to pure stock.

Uh, which forum? I thought that's what I was doing by posting here.

No, LGUP is the Windows only software to flash a KDZ (i.e. the full phone). Uppercut is an app to assist in using LGUP. Downloads and help in this XDA forum. You only need it if you brick or otherwise need to revert to an earlier S/W version (i.e. "Update"). Link in my last post is for the actual (pre-November 2016) KDZ (for US996) that the Dirty Santa exploit works on.Uh, which forum? I thought that's what I was doing by posting here.

Ohhhh... I think I get what you're getting at~
Also, loving this extended battery I got on the phone. Did a first full charge on Monday... and even today on wednesday with my usual usage, it's still got life left in it. that is why I wish more current phones were build like this. It's also another reason I despise sealed battery phones.

Ya, I'm a Motorola fan myself but the "user replaceable" battery has been is gone from their line-up for awhile. Unfortunately, this is soon to be for most every device. Hope you fare well...

After what I dealt with, regarding the MXPE, I never want to even think about another Motorola phone. the last straw was when Lenovo took over and sued every distributor of their parts, so that what used to be a reasonably complete kit for an OEM replacement battery for $15 then became a chinese knock-off for $50 sans the replacement glue to hold it in place, let alone to re-apply the backing of the phone. And of course, no way to link up multiple batteries in parallel or something to even have halfway decent battery life. Even when I was able to play it, that thing went from full charge to flat on sixty minutes of Pokemon Go. That's just unacceptable.
I can't help but think that a 3,000mAh battery dying in only an hr is due to something else you may not be considering.. Even GPS navigation lasted hours on same phone when I got it, it's actually a decent device in itself. It also had no issues playing PokemonGo, for the time I could force myself to play it (not a diehard fan)

For the brief time I had a part time job as a delivery driver, using maps for navigation was not much better. I usually had to plug it in to the car charger or the external battery after about an hour into what would be about 9 hours of driving a day. And if not the car charger, it would happily wreck cables and drain the external battery before it would even go up a %'age on the phone itself. And people wonder why I'm skeptical (at best) about battery cases.
During that time, the battery would just get hot and refuse to charge at all, but happily drain the crap out of the external bank! nevermind at times just crashing while navigating, which would trip me up or force me to pull over and try and get the directions going again.
