I did prorate the excess and the family maximum contributions. TurboTax has a maximum contribution calculator that also provides the prorated HSA amount that each of us could contribute. The contributions I made to both of our HSA accounts matched the TurboTax maximum contribution calculations. I checked our birthday dates in the personal information to ensure that they were correct. I also confirmed that our 2021 HSA contributions did not exceed the maximum contribution amount. It appears that the software may have a glitch based upon my experience.
