After you file

I want to file an amended 2021 federal return, BUT...

 

I can't find "Amend a filed return" on my home page.  Under "Tax returns and documents" there is no Amend option when 2021 is selected. When I go into my federal forms and click "Other Tax situations" I do see an Amend option, but the only year offered is 2020 or earlier.

 

I could wait until Monday, but I'd like to get this finished as soon as possible.
