Amending taxes to reflect repayment of social security disability

[Phillymcgregor]

Hello! I received a lump sum for social security disability, and then had to pay a portion of that to my employer. I received about 30,000 and repaid 20,000. I received the lump sum in 2023 and repaid it in 2024 to my employer. I tried adding this to the repayment over 3,000 deduction area, but this is just adjusting my standard/itemized deduction and not social security taxable amount. This is only adjusting my income by 8,000 and not the full 20,000. Is there a different way to add this? I am using turbo tax software. Thank you!
