tax return associated with sign up bonus repayment

Hi tax expert,

 

I have a question about income tax repayment and wonder if you could help answer. 

Here is the thing: I received a 50000 sign up bonus when I joined a company in Oct 2020. I paid back a quarter of it, 12500, when I left this company in Feb 2022. After paying back this money, I got a repayment receipt. I contacted them several times to get an adjusted W2 form but was not able to get one unfortunately. I want to fill the tax return associated with this bonus repayment when filling 2023 tax. Is this feasible without an adjusted W-2? If so, could you let me know how to do that? Thanks!
