WI Schedule CS Line 7 - Isn't it supposed to be $3860 for all married filing jointly taxpayers?

Why doesn't TurboTax enter $3860 in Line 7 of the WI Schedule CS (2023)?  I think that's all this line is about.  I'm married filing jointly, so I should enter $3860.

This results my contribution for this year going to Line 16: Carryover to future years, which results it in being a carryover to 2024 on Line 37.

 

It does this for one of my kids but not the other.  So when Turbotax does the Tuition and Fee Expense and College Savings Worksheet, it only registers the contributions for one kid.
