Re: W-2 Box 12 I have two separate entries 401K contributions two tax years (intuit.com)
"There are many posts here each year regarding this issue. Unfortunately, the only solutions in TurboTax are either to omit the entry of the prior-year amount or to combine the amounts on a single code-D entry and then ignore the warning about overcontributing. The warning about overcontributing has no effect on your ability to file. Omitting the prior-year amount would be extremely unlikely to affect your tax return since doing so would almost certainly not affect your eligibility for a Retirement Savings Contributions Credit given that the combined deferrals exceed the annual deferral limit.
Sorry , I miss type. I mean I could not find the category on 12a for D22 amount.
D22 refers to a 401k contribution (code D), made late for 2022 .
I think the way to deal with it, is to not enter that particular line&amount at all.
But wait for @dmertz to comment sometime today or tomorrow, he knows the details that I only hazily recall.
