Assist with Social Security Overpayment Relief

I need help paying my overpayment with Social Security. I was working and I didn’t get my social security check for May 2024 and I had to go to the local social security office. They told me they cut me off and I had overpayment. They also said I owed them 20 thousand dollars, which I currently don’t have. I am currently unemployed and am on a fixed income. Any help toward the overpayment would be really appreciated.
