How do I file with TurboTax for 2019?

[kmorberg]

Did not file in 2019, but got an extension to file my 2019 tax return no later than 10/15/2020.  Now I want to use TurboTax to file that 2019 return.

You can use TurboTax to complete and e-file a 2019 tax return up through October 15, 2020.  After that date the 2019 tax return can only be printed and mailed and you will need to use the desktop editions.  The 2019 online editions will shut down shortly after 10/15/2020 to make way for the 2020 online editions.

you can't file for 2019 in 2019. you must wait until after Jan 1, 2020, and for your tax documents.

If you mean you did not file a 2018 return in 2019 then to efile the 2019 return you would use a single ZERO for the 2018 AGI.
