1099R Code P

[Landlocked]

In March of 2022 I over-funded the Traditional IRA for 2021 and received the 1099R with code P and recorded that in my 2022 tax return. The retirement fund reimbursed before that 2021 tax return deadline. I did not ammend the 2021 return as was suggested by Turbotax. Now it is too late to ammend the 2021, I think. I have received a notice from my state that that same amount on the 1099R was reported to them by the Federal IRS as an adjustment to gross income.  This is the Reason for Adjustment:

"Your Adjusted Gross Income does not match your federal return or is does not include all income as reported by the IRS.

So, since my 2021 return should have been amended and was not amended, should I now amend the 2022 return by removing the 1099R from it? 

I could have a real mess here because the state already reduced the 2025 refund for the amount they say is taxable. I am super confused!

The IRS generally allows you to file an amended return (Form 1040-X) to claim a REFUND within 3 years from the original filing date or 2 years from when the tax was paid, whichever is later, but if you need to correct the income you should file an amended return.

However, since the state said they made the adjustment due to the change in the federal income, the IRS may have already made the adjustment.  You should review the notice that the state sent you carefully, and if you do not agree with the assessment you can prepare the amended returns and submit them to the state with the corrected amounts.  (Note because you did not report the income correctly, interest was most likely added to the amount you owed.)
