Does severance delay my unemployment claim? - 6 months and counting

I was offered severance of 16 weeks after being let go as a software tester and I am unsure how it affects benefits. I would rather hear the honest version than the polite one. I have a mortgage and need to plan. How did your state treat it?

Before signing, I asked a friend who is a lawyer to look at the agreement. It was a short conversation and worth it.
