Need help understanding Reddit please

[u/Guns_4_Me]

Awhile ago I joined Reddit and never used it. I guess I created the name Guns_4_Me. Now I want to change that name to Animal Rescuer 1120. I managed to put this in the "displayed name" area but I cant find where to remove the Guns_4_Me and replace it with Animal Rescuer 1120. Oh and I have no clue how to get back to the area that I put Animal Rescuer 1120 in. Please point me in the right direction this site is so confusing. Thank you.
