Sounds like my husband's pension. He got to buy extra time. The after tax money he sent in is tracked by the pension and a part of each retirement check he gets is not taxable. The 1099R he gets at the end of the year breaks it out. Ask the pension plan. You don't account for it when you paid it in. It's when you take it out you shouldn't pay tax on it again. The plan knows and should report it right.
