I made the same 401K excess contribution error after switching jobs. I caught the error before filing and want to take care of it as much as possible in the 2022 tax filing. Is it best to get a revised W-2 from my current employer, or do I just report the excess 401K contributions in my 2022 Turbo Tax filing as you said, and then report any gain realized on the excess contribution in 2023 (using the 2023 Fm1099 that I should be sent by the 401K custodian)?
