Check your spam or junk mail folders on your email account for TurboTax emails.

Verify your email address for the TurboTax account.  See this TurboTax support FAQ for updating your account - https://ttlc.intuit.com/community/account-updates/help/how-do-i-update-my-turbotax-account-informati...

 

Since the IRS has rejected both the actual 2019 AGI and the 0 for the AGI your only other option is to print and mail the tax return.

Note - If you have no taxes owed or are receiving a tax refund there are no penalties for filing a tax return after the due date.
