Form 8889 Not Calculating Correctly for My Situation

We are using the desktop version of TurboTax Home and Business. Both my wife and I are over 55 with HSA accounts. We had a family HDHP from Jan - May 2023 tied to my HSA account, then I switched to Medicare coverage, while my wife switched to an individual HDHP from Jun 2023 – Dec 2023.

 

As a family, we should be eligible to contribute $8,750 to our HSA accounts for 2023. I have contributed $3,645.83 to my account (family limit prorated over 5 months). My wife should be able to contribute the difference ($5,104.17) to her account. However, when I enter these amounts in the software, TurboTax is indicating we made an excess contribution of $2,118, and the program is attempting to charge us an extra 6% tax.

 

I am pretty sure that my numbers are correct, and TurboTax is making a calculation error here. How do we get this resolved?
