How do you report hours that vary week to week? - any advice?

My hours change every week at my new part-time job and I am afraid of reporting wrongly. It has been weighing on me all week. Sometimes my paycheck is late by a week. 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.
