Severance and unemployment, do they overlap? - first time posting

I was offered severance of 17 weeks after being let go as a store manager and I am unsure how it affects benefits. There are 17 people counting on me, so I am trying to be careful. I have a mortgage and need to plan. Did you file straight away?

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.
