Told I owe money back on my benefits after 16 years as an office manager

The agency says I reported earnings incorrectly, but I think I followed the instructions. The letter mentions an appeal window and a repayment plan. Has anyone disputed one of these?

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.

Read the letter for the appeal deadline and act on it, even if you think you will end up repaying. Then ask about a payment plan.
