@userwildflowervip asked: "I did not file taxes last year so I do not hav an agi to enter for 2019. What do I do because it wont let me e file without it? Can I use my agi from 2018 since I dont have an agi from 2019? "
No, you do NOT use the 2018 AGI.
If you didn't file a 2019 return, then you have no 2019 AGI, so you use an AGI of 0 (zero) when verifying your return when efiling.
I entered zero for my 2019 AGI because I did not file in 2019 and I was rejected twice with the same error for incorrect AGI. What now?
You will have to print and mail the 2020 tax return. See this TurboTax support FAQ for how to print a tax return for mailing - https://ttlc.intuit.com/community/printing/help/how-do-i-print-and-mail-my-return-in-turbotax-online...
