I got the same IRS response this week saying 'ITIN issued after due date of original filing' (after 18 weeks) for the amendment that included spouse ITIN to increase the standard deduction on 2021 returns (filed during sep 2022).
I don't understand whether this is mistake by the IRS person who processed my amendment or my scenario was not a right one for amendment? Any advice or any one challenged the IRS decision in similar cases?
