I printed my federal and state returns for review and now program says that "Way to go,....! You filed your 2021 taxes.". How do I go back into program to make changes?

To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/

When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state. 

This will take you back to the 2021 online tax return to make any changes before filing the tax return.

If you haven't efiled or mailed your return you can go back 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 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.
