Got severance, how does it affect benefits? - any advice?

I was offered severance of 13 weeks after being let go as an HR coordinator and I am unsure how it affects benefits. Thank you in advance. I have a mortgage and need to plan.

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.
