Why is TurboTax saying I get a Child and Dependent Care Credit for 2023 childcare expenses paid in 2024? When I complete 2441 Worksheet A manually, I get no credit

I believe TurboTax has problems with the Child and Dependent Care Credit. I have qualified childcare expenses from 2023 that I paid in 2024. However, I believe I also maxed out my 2023 credit already. When I completed 2441 Worksheet A manually, I get the result that I can claim no additional care credit. TurboTax seemingly never checks this fact (even though it has that information about my previous year's return), and it happily suggests I can claim these as a tax credit. Does TurboTax fill out Worksheet A in the background? I would love to know what information it is using.
