Got an overpayment notice, what now? (update)

After 8 weeks of benefits I got a notice saying I must repay some of it. It has been weighing on me all week. I did not notice any errors at the time.

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.
