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

I picked up part-time shifts as an operations analyst and I am confused about how to report them. I am in Cincinnati, in case local advice matters. The form asks for gross earnings, which I do not see until later. Who can I ask without risking my claim?

The claimant handbook has worked examples for part-time pay. Mine was clearer than the phone line.

Report honestly and keep your stubs. An honest small error is much easier to fix than a missing report.
