IRS notice transfer error

IRS says that form 8812 had an error in transferring Dependent Credit. It seems like TurboTax did make the error in transferring schedule 8812 Part I-A line 5. How do I correct this error or TurboTax calculation?

 

However for the tax year 2021, joint filer can claim both the Child and Dependent Care Credit (CDCTC) and the Child Tax Credit (CTC). I had one under age of 5 and one above 6. So that's $6,050. for AGI at$160,730 is reduced by $600. That is $6,050. I don't understand how IRS came up with a different number.

The Dependent care Credit was $2,500.
