Deductions & credits

Thanks JeffreyR77.  I see how to do this as an "Other Deductible Expense", but it is then entered as a deduction for 2020 (below Federal standard deduction), and not a credit. As I understand Publication 525, I am allowed to calculate the tax on repayment amount take as credit on Schedule 3, Line 12d (note IRC 1341 in entry line).  However, I have not found the way to do this in TurboTax Deluxe.  I can view the Schedule 3 form under "Forms", but seems I cannot make changes.
