I have a very similar situation... (married filing jointly) : 1 master HSA account (for the family) with a total contribution of $4750.
Both adults over 55, and yet TurboTax says I have contributed excess of $1550, even though we have documentation saying we only contributed 4750.
Before I file, I want to be certain this is a turbotax error and not my error.
It's not easy to find or check in TT
