I did not efile last year (for 2020), so there was no efile pin from last year. I mailed in my return before the deadline and sent a check which was cleared by mid May, 2021, so I assume IRS received and processed my return in May 2021. I efiled this year (2021 return) before April 18. With the above scenario, even though I entered the right AGI (from line 11 of last year's return) and entered a 5 digit PIN (new this year), why am I getting this IND-031-04 error and how do I fix and resubmit ?
It got rejected twice with the same error. Is there a workaround so that I can still efile ?
