I'm still confused about excess 401K deferrals. I changed employers in 2021 and thus over contributed to the 401Ks. I notified both employers who referred me Fidelity who has informed me it's too late to make changes. So I added the amount to Other income s instructed when I completed my 2021 return. Do I need to go back to one of the employers and have them do something? Back to Fidelity? How will one 401K plan know that the other over-deferred? Do I just forget about it as I have reported the excess deferral as income in 2021? I don't understand what my next step is if anything. Thanks for any help you can provide.
