Overpayment letter from the unemployment office

The agency says I reported earnings incorrectly, but I think I followed the instructions. I would rather hear the honest version than the polite one. 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.

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.
