1099-R says taxable but it was after-tax money
I have a complicated situation. My employer pays the 401K match in January of the FOLLOWING year. So for tax year 2022, I contributed the maximum $61K ($20.5K pre tax, rest after tax), and in January 2023 my employer matched me $12,200 (lump sum) for year 2022. Because of that, I went over and therefore I received a check of $12,200 and a 1099-R saying it is taxable in year 2023. What I feel is wrong is that the 1099-R is saying it is taxable even though it was from my after-tax money... should I say it is not taxable in my return?
