How do you report hours that vary week to week? - 24 weeks in

I picked up part-time shifts as a software tester and I am confused about how to report them. There are 6 people counting on me, so I am trying to be careful. The form asks for gross earnings, which I do not see until later. Who can I ask without risking my claim?

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.

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.
