@SusanY1 What if I forgot to add the IP PIN in a form that was mailed? Can I do something about it to avoid delays? This is for a previous year (2021) and this would be the last season I could file for that year.
Could I send a letter to the IRS or contact them somehow to prove my identity?
2022 and 2023 returns did contain my IP PIN. Do you think that they will see that the information for all three years matches and be able to identify (and not reject) my 2021 return with the missing IP PIN?
Any thoughts and suggestions will be greatly appreciated.
Best
