Thanks @macuser_22 . I called my 401k administrator, they said their cut off to report excess contribution was March 15, 2021. I unfortunately did not know this and missed it. They said they are not allowed to issue a refund now and asked to get advice from a tax advisor. Please let me know if this will be a good next step for me. 1. Add the excess 2020 contribution as Miscellaneous income when I file today 2. Looks like I may not receive 1099-R since the current administrator does not know how much I overcontributed? So when I withdraw the excess amount during retirement, I will pay tax again (double taxation! :-() - correct?
Thanks again
