Excess deferrals to my 401k in 2023.
I had excess deferrals to my 401k in 2023. I notified the plan administrator and was given a check for the excess deferral, before April 15. I've corrected my tax return to show the excess deferral as earned income. This all seems to be OK.
But, how can I show on my turbo tax return that I contributed no more than the maximum allowable amount to my 401k in 2023? Correcting the number in box 12b of my W-2 does not seem to be the answer, since the IRS has a copy of the W-2.
