I have basis in my IRA from contributions made many years ago. When entering 1099-R for IRA distribution this year, I erred entering the basis amount and FMV data. The Form 8606 was automatically calculated with this misinformation.
I cannot find a way to go back to correct the basis and FMV values.
I have deleted the 1099-R and re-entered it but the questions for basis and FMV are not asked again. The Form 8606 re-generates with the old basis and FMV data.
I need a way for the old data to be removed or corrected.
Any suggestions other than creating a new account would be appreciated.
