Wage reporting when hours change weekly after 8 years as a store manager

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

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.
