You are eligible for unemployment benefits if you quit for good cause attributable to your employer. If the benefits are denied, you appeal and a determination is made via a telephonic arbitration. The best thing to do is apply for the benefits. This can be done online here:
You should absolutely apply for the benefits. Based on what you said about being told to stop coming in to work before the effective date of your resignation, you should read Porter v. UAC (link below). I would also suggest that you read the guide I wrote (link below) to get a better understanding of entitlement to benefits in the U/C system. If you wind up having to go to a hearing, I would also suggest that you hire an attorney to represent you, because undoing mistakes by appeal is very difficult.
