I noticed TurboTax seems to be applying an extra $100 or so to my estimated taxes?

I noticed after putting in my estimated taxes for 2024 Turbotax is putting an extra 100 or so in my estimated tax payments. I'm using turbotax online. 

 

I checked and while I did carry some of the overpayment from from last year, it wouldn't be enough for the number I'm being shown.

 

What could be going on? Is there anywhere I can see a break down of how it is calculating this? Can I check my previous tax return?
