We decided to add more to my wife's IRA. How do I update the return in Turbo Tax, which only lets me see a PDF (I have not filed yet)?

To access your current or prior year online tax returns sign onto the TurboTax website with the userID 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 2019 online tax return.

Thanks. That worked.
