After you file

Just want to confirm that it did work for me. IRS accepted my return. I guess it's only used by IRS to automatically verify a user. It doesn't matter much what you enter as long as the system accepts your return. 

Thanks for your help.


Good news!  You're welcome.

  Yes, you could use Option 1, and then enter a 2019 AGI of 0 since the IRS computer does not yet know the 2019 AGI in its database since your 2019 return has not been processed. 

 

Option 4 (didn't file last year) while technically not correct, would have worked, too, since it would have fooled TurboTax into using a 2019 AGI of 0.   If one tells TurboTax they didn't file a 2019 return, it would enter a 2019 AGI of 0 automatically in the background.
