I keep getting rejected by the IRS because I put 0 for the AGI from last year but I didn’t file last year?

If you’ve tried entering zero because you did not file last year, but still it still does not work, you can still file a paper return by printing out copies of your federal and state returns and mailing them. We’ll include File by Mail Instructions on where to send your returns and what forms, if any, you need to include.
