Maybe I should have been more specific. You can't e-file a $0 income return with the IRS. I saw posts from others who attempted a e-file a $0 return for 2019 and the IRS computers would not accept it. Also, from what I've been told by those who mailed a paper return to the IRS with $0 income on it, looks like it was never even processed, as nothing shows up on the filing history for the tax year a $0 return was mailed.
