Told I owe money back on my benefits (Pittsburgh)

The agency says I reported earnings incorrectly, but I think I followed the instructions. I have read a lot of threads here and could not find my exact situation. I cannot afford to repay it all at once. Are payment plans possible?

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