My wife and I both have HSA accounts through our employers. Mine is a single account and my wife's is a family account. We are both covered by HDHP health plans. The combined total of my, plus my employer's, contribution to my single HSA account was $2,725. My wife's total contribution to her family plan, including her employer's contribution, was $4,600. Those values are reflected in our W-2's and in the forms that TurboTax displays for entering the HSA information. We did not contribute anything additional, are not on Medicare, and did not use any funds for medical expenses. However, when the screen comes up for our over contribution, rather than stating $125, it states we over-contributed by $2,750. I have tried re-entering information and logging out and back on, but it keeps stating we over-contributed. Per the IRS rules for 2021, we were allowed, as a family, to contribute a total of $7,200 to our respective HSA's, regardless of how it was divided between the two of us.
