Overpayment letter from the unemployment office

The agency says I reported earnings incorrectly, but I think I followed the instructions. I have been trying to stay organised about it. I cannot afford to repay it all at once. Has anyone disputed one of these?

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.

Keep everything in writing and save the confirmation numbers. It saved me later.
