Overpayment letter from the unemployment office - first time posting

The agency says I reported earnings incorrectly, but I think I followed the instructions. I cannot afford to repay it all at once. 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.
