HSA Excess Deduction Calculation

Not sure what I am missing.

TT figures my max contribution as $675. I put in $1296 or I am over $621.

TT figures my spouse (married filing jointly) max contribution at $4846. She put in $4550 or under $296

Moving to the next screen TT then states I have over contributed $917

TT seems to be adding the over and under ?

Anybody know what I am missing and why my over is not either $296-$621 or maybe just $621
