I am doing a claim a right salary repayment of $5K as a other itemized deduction on Sch A. TurboTax is including the $5K on line 10 of the 8960 - doesn't seem correct?

The salary repayment (originally paid in 2020 and paid back in 2023) has nothing to do with investment income, so I don't understand why that would carryforward to the form 8960 - is this a TurboTax error?
