Severance and unemployment, do they overlap? after 17 years as a payroll clerk

I signed a severance agreement and I am worried about how to report it. Any experience at all would help. I have a mortgage and need to plan. Did you file straight away?

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

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