Does severance delay my unemployment claim? - 6 weeks in

I signed a severance agreement and I am worried about how to report it. I am in Portland, in case local advice matters. I have a mortgage and need to plan. Who should I ask before signing?

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.
