I left the company and repaid the relocation expenses, including tax assistance. So, I paid taxes for the relocation I returned. How can I claim a refund of the taxes?

if you repaid the relocation expenses in the same year you got them the adjustment must be reflected on the w-2 for that year. otherwise under IRC 1341 if you repaid that expense in a subsequent year and it was more than $3000 you get the following choices. a) take an itemized deduction on schedule a line 26 for the repayment in the year repaid or b) recompute your taxes for the year you got reimbursed by excluding such reimbursement from your w-2 taxable wages. then in the year repaid you take the amount as a tax credit on schedule 3 line 13d.  note this is based on 2022 forms

Correction you take the amount of reduction in your tax liability as a credit not the amount repaid.
