Does severance delay my unemployment claim? after 4 years as a delivery driver

I was offered severance of 4 weeks after being let go as a delivery driver and I am unsure how it affects benefits. I have a mortgage and need to plan.

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

Rules differ by state. I called the claims line and asked directly, then wrote down the answer and the date.
