Turbotax says excess HSA contribution - not true

My husband and I both went on Medicare this year. We are both self-employed. 

 

We had a joint high deductible health plan in January.  February and March I had a high deductible health plan and he was on Medicare. In April-December we were both on Medicare. 

 

We jointly contributed $2325 to a single HSA.  Turbotax says he can contribute $775, so I gave him that share, leaving me claiming the remaining $1550.  Turbotax says my contribution could be $1663, which is more than I put in. 

 

Yet it says we contributed $609 too much.  I have tried starting over at the screen "Tell us about the health-related accounts you had in 2024" but it still says we had an excess contribution.
