Told I owe money back on my benefits

The agency says I reported earnings incorrectly, but I think I followed the instructions. I cannot afford to repay it all at once. Who should I talk to first?

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.
