Overpayment letter from the unemployment office (update)

I received a letter saying I was overpaid about $150 on my claim. It has been a long 2 weeks. The letter mentions an appeal window and a repayment plan. Are payment plans possible?

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.

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