Reporting part-time earnings while on benefits (Seattle)

I picked up part-time shifts as a medical assistant and I am confused about how to report them. I am in Seattle, in case local advice matters. Sometimes my paycheck is late by a week. Did anyone get an overpayment notice from a mistake?

Keep everything in writing and save the confirmation numbers. It saved me later.

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.
