Thank you for considering and replying to my comment. To clarify: the mail I received from the IRS was a notice informing me of "Changes to your 2019 Form 1040," so they had indeed received and processed my return. They even sent me an unexpected and inexplicable refund check for $7.15. So I maintain that the problem does not lie with an AGI not being entered into their system. However, the first-time filer-zero option worked, thankfully, and I am grateful to those posters who mentioned it here.
