Severance and unemployment, do they overlap? - any advice?

My employer is paying severance in instalments and I am not sure whether to file now. It has been weighing on me all week. The agreement mentions a release and a payment schedule. How did your state treat it?

Keep everything in writing and save the confirmation numbers. It saved me later.

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