Overpayment letter from the unemployment office (Omaha)

The agency says I reported earnings incorrectly, but I think I followed the instructions. Thank you in advance. I cannot afford to repay it all at once. Who should I talk to first?

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.

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