Does severance delay my unemployment claim? (update)

I signed a severance agreement and I am worried about how to report it. The agreement mentions a release and a payment schedule. Who should I ask before signing?

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

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
