Sorry Expert @RobertB4444
Your 1099-R from an IRA is not going to reflect any non-deductible contributions,
All that information is on your Form 8606.
@Pistol71
Form 8606 is cumulative, so you only need the most recently filed Form 8606 to know you prior years basis.
IRS requires you to keep all copies of Form 8606 forever.
IRS says:
"All distributions from your IRA will be taxed unless you can show, with satisfactory evidence, that nondeductible contributions were made."
