How do you report hours that vary week to week? - first time posting

I picked up part-time shifts as a procurement assistant and I am confused about how to report them. I have read a lot of threads here and could not find my exact situation. 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.

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