Solved
I paid and printed my tax return. Turbotax thought I already submitted my return in mail. So I can only amend my tax. But I actually would like to e-file my return (as a fresh return) but not amend. How do I do it?
Sounds like you are ok. For anyone else finding this post.....
If you haven't efiled or mailed your return you can go back and change anything and switch to efile. Do not click on Amend!
Click on Add a State to let you back into your return.
From Tax Home (the first screen you see after you sign in), scroll down to Your tax returns & documents. You may have to select Show to open the drop down.
Select 2020, and then select Add a State (you're not actually adding a state, this is just the workaround).
Then when you are ready to file you can try to switch to efile.
