Extra deferral deposited during the year

Hi

Question for 401 gurus.

Non-HCE participant deferred $8,000 on 2022 w-2 (1,000 per paycheck) and terminated after 8 paychecks.

Just found out that they deposited another $1,000 without a paycheck i.e. $9,000 was deposited during 2022.

As only $8,000 was on the w-2, how is this corrected?

Earnings are pennies as all invested in cash.

Thanks

Thank you for the input

just curious - if this was a NHCE, how on earth did they deposit the additional $1000 without it going through payroll?

Your guess is as good as mine.

Someone probably copied the prior payroll without checking the current one.

And then clearly the employer is not balancing the books, because the extra 1000 should stick out like a sore thumb!!

Sometimes you miss it if you are making a lot of dough. I will suggest Brenda's approach.
