Got an overpayment notice, what now? (Cleveland)

After 11 weeks of benefits I got a notice saying I must repay some of it. This is my first time dealing with any of this. The letter mentions an appeal window and a repayment plan.

If you are unsure, free legal aid in your area may help for this kind of notice.

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