Told I owe money back on my benefits, office manager here

The agency says I reported earnings incorrectly, but I think I followed the instructions. I do not usually post, so bear with me. The letter mentions an appeal window and a repayment plan.

Collect your pay stubs and certification records for the weeks they name. Mine showed the error was a date mix-up.

If you are unsure, free legal aid in your area may help for this kind of notice.
