Got an overpayment notice, what now? after 18 years as a project coordinator

After 26 weeks of benefits I got a notice saying I must repay some of it. There are 18 people counting on me, so I am trying to be careful. I cannot afford to repay it all at once.

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

Thanks for writing this out. I went through something close to it 8 months ago, and it settled down once I kept a simple log of every call and form.
