WPA2 PSK is just a designation for which security protocol is selected, it's simply identifying the type of WiFi network. It isn't the actual password you need to enter in your laptop's prompt so it will be able to connect itself to your hotspot WiFi network.
If you need help setting this up, instead of fighting with it you might be better off just taking your phone and your laptop somewhere to have this done for you. Local libraries often have 'tech help' nights, some community colleges have basic tech classes, or even a nearby phone or computer service shop might help you for little to no cost. Or just ask a tech savvy friend.
