How to I get turbo tax to unlock my return..I finished and printed yesterday I am mailing my return, and realized an error that I need to fix but it won't let me back in

To change a return If you haven't mailed or efiled yet, see

https://ttlc.intuit.com/community/tax-topics/help/i-want-to-change-a-return-i-ve-printed-but-haven-t...

If you haven't efiled or mailed your return or it rejected you can go back in and change anything you want.  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).
