Overpayment letter from the unemployment office - first time posting

I received a letter saying I was overpaid about $1050 on my claim. It has been weighing on me all week. I cannot afford to repay it all at once. Has anyone disputed one of these?

If you are unsure, free legal aid in your area may help for this kind of notice.

Collect your pay stubs and certification records for the weeks they name. Mine showed the error was a date mix-up.
