After you file

Well keep going.   Let it check to confirm your return was filed.   You can't amend unless the program knows your first efile was accepted.  

 

You can jump around.  You don't have to stay on this screen.  You can go back.  Just click on the tabs at the top.  Like click on FEDERAL TAXES then go to Other Tax Situations and scroll down to Other Tax Forms - Amend.  Like on a screen shot several posts above.
