Can you help me find this info, Dependent care benefits received for 2020 and deducted on your return and/or excluded from your income (2020 Form 2441, lines 24 and 25)?

It would probably be easier to make your entries for Dependent Care Expenses you paid in 2021 in the TurboTax interview.

 

Click this link for instructions on How to Enter Dependent Care Expenses.

 

Once you choose the dependent and enter the amount paid in 2021, you will then enter caregiver info.  

 

TurboTax then asks if you paid any care for 2020 in 2021.
