Told I owe money back on my benefits, janitorial supervisor here

I received a letter saying I was overpaid about $1050 on my claim. This is my first time dealing with any of this. The letter mentions an appeal window and a repayment plan. Are payment plans possible?

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

I asked for a waiver and a plan in the same call, and they gave me both forms. It was less scary than I expected.
