Thank you, but tried that. TurboTax only allows an AGI input or print and mail. 
What next?


If the IRS rejected the e-filed return with a 0 entered for the 2019 AGI then your only other option is to print and mail the 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...
