Reporting part-time earnings while on benefits

My hours change every week at my new part-time job and I am afraid of reporting wrongly. Any experience at all would help. The form asks for gross earnings, which I do not see until later. Did anyone get an overpayment notice from a mistake?

I estimated and then checked my pay stub. When there was a small difference I wrote to the agency to correct it.

In my state the question was about the week I worked, not the week I was paid. Read the wording on your form carefully, or ask the claims line.
