State tax filing

The TurboTax screen relating to this issue doesn't quite match up with the instructions in the 2023 Student Loan Repayment Tax Credit Worksheet.

The instructions for Box D of the worksheet state:

Check this box if you previously received the EOTC for tax year 2019, 2020, or 2021 for a bachelor’s or associate degree in science, technology, engineering, or mathematics (“STEM”) to indicate that you may be eligible to receive the one-time increased credit, up to $3,500. Also see the instructions for line 5 below. 

So, you wouldn't check Box D (on the worksheet) if you've already received the increased credit.

However, this isn't specified on TurboTax's Credit for Student Loan Repayment - Degree Information page:

Answering the second question Yes would appear to be the equivalent of checking Box D, and so will allow the $3,500 credit, even though it's a one-time credit you've already received.

Try selecting No Entry on the second question, and see if you receive the correct amount of credit.
