Does severance delay my unemployment claim? - any advice?

I signed a severance agreement and I am worried about how to report it. I am in Seattle, in case local advice matters. I also wonder about the job-search requirement. How did your state treat it?

I filed on day one anyway and reported the severance honestly. The agency decided what to do about the timing.

Some states only count certain kinds of severance. A local workforce centre could tell me which.
