Overpayment letter from the unemployment office, bank teller here

The agency says I reported earnings incorrectly, but I think I followed the instructions. This is my first time dealing with any of this. I cannot afford to repay it all at once. Are payment plans possible?

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

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
