Hi, I had made an excess contribution to my 403b plan in 2020. I didn't catch it until May 2021 (as the tax filing deadline was extended); but by this time, the deadline to request a ROE (Apr 15) has already passed. So I filed the taxes as it is - the IRS didn't flag the excess contributions.
If a 1099 had been issued, I would have included it in the 2021 income. Since no 1099 was issued, I am trying to figure out what I should do.
option 1: Should I just report the excess and hope the IRS would figure it out? If yes, where should I report it in turbotax? And how should I figure out the gains on that amount - since it was 403b, the money was periodically deposited/investment - how will I determine which amount to take for the excess contribution?
option2: If I cannot just report the excess contribution (without a 1099), then what should I do... my holding company and the employer cannot help.
I will appreciate any guidance.
