Could you be more specific and provide some pertinent details? Vague references can only result in equally vague suggestions.
-- What is the specific model I.D. of your Note 10.1? (i.e. some have a SCH-i925x designation, some GT-N80xx)
-- Where did you obtain the ROM you used, and are you sure that it specifically matched your model? ROMs are not interchangeable between different models or different variants, they are very specific.
-- It's also vital you used the correct version of TWRP. They're also model specific. There's an Exynos and a Qualcomm version of TWRP for Note 10.1 devices.
From your description, it sounds like either the flashing process failed in some way (posting the end result Odin log might reveal something notable) or you used a ROM that doesn't match your model I.D. Flashing an incorrect ROM will result in something like that a boot loop or failure to boot up at all -- with no working operating system your Note can't boot up so it just fail. Try downloading the appropriate Samsung stock ROM from sammobile or frija, flash that onto your Note to restore it back to working condition. Flashing a stock, Samsung ROM will install a clean copy of Android and a stock Recovery so when you get your Note working again, you'll need to start over if you want to root and install a custom ROM again. Just be sure everything you flash onto it is for your specific model.
