NO, do not click on Amend, or you'll have problems.
If TurboTax thinks you might be finished, the return interview may be closed. If it is, here's how to open it back up to resume:
- Log in and at the Tax Home or in the section "Your Tax Returns & Documents" for 2020, look for a link "Add a State."
- Click on "Add a State." (you don't really add one. That's just to open your return back up.)
