Overpayment letter from the unemployment office after 15 years as an accounts payable clerk

I received a letter saying I was overpaid about $1150 on my claim. I have been trying to stay organised about it. 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 got easier once I kept a simple log of every call and form.
