How do i update a return that says ready to mail

[HeatherPLO]

Are you wanting to switch to e-file?  Please see the Help Article here for switching from mailing your return to e-filing.

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 to finish 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 2021, 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.
