File one 8606 for the most recent year you made a contribution (presumably, 2023 ?)
Enter the correct amounts on Line 1 and Line 2.
Explanation: Did not include Form 8606 with tax return.
Your record will then be up to date.
If IRS raises and issue (unlikely), you can deal with it later
Your collection of Form 5498 records becomes invaluable in case of an IRS question.
