Got an overpayment notice, what now? (Madison)

After 13 weeks of benefits I got a notice saying I must repay some of it. Thank you in advance. The letter mentions an appeal window and a repayment plan. Has anyone disputed one of these?

Read the letter for the appeal deadline and act on it, even if you think you will end up repaying. Then ask about a payment plan.

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.
