After you file

Why do you need the 2018 AGI?   Are you preparing a 2019 return?   You cannot efile a 2019 return at this point in time.  And Online TurboTax is for 2020 returns only; you can no longer prepare and file a 2019 return online.  If you're preparing a 2019 return now, it has to be done in the 2019 desktop software (CD/download), then printed, signed, and mailed.

 

Perhaps you need the 2018 AGI for some other reason, but I'm just making sure you aren't trying to prepare and file a 2019 return by mistake in the current Online TurboTax.
