You can always file by mail. But if you want to file by mail, you can't have your Turbotax fees deducted from your refund, and you can't have your refund paid to you on a debit card. Go back and revise those choices.
The first time you e-filed, you chose a 5 digit e-filing PIN. To verify your identity now, you must either use the same 5 digit e-filing PIN, or your last year's AGI (2020, not 2019 or 2021). In some cases, if your 2020 tax return was not processed in time, your 2020 AGI won't be in the database and zero will work. But sometimes, an AGI problem can't be fixed by the taxpayer, it's just a problem with the IRS, and you have to mail your return.
