TurboTax tells me that we've over-contributed to our HSA's by $730 for tax year 2020. My math says I'm 99 cents under the contribution max. Any help figuring out where I'm going wrong (or where TT is) would be appreciated.
DH became eligible for Medicare in September and I followed in October. We had family HSA-compatible coverage January-August, and I had solo HSA-compatible coverage in September.
H contribution max = (8/12)*7100=4733.33 + (8/12)*1000 catch up = 666.66.
My contribution = (1/12)* 3550 (for the month I had single coverage)= 295.83 +(9/12) * 1000 catch up = 750.00
Total theoretically between all HSA accounts: 6445.82
Actual contributions were DH 1666 and mine of 4778.83 for a total of 6444.83.
TT says we over-contributed $730.
