First unemployment deposit is late, what should I check? - what worked for you?

I filed my claim 20 weeks ago after being let go as an accountant. Any experience at all would help. The page shows my claim as open but no payment date. Is there a step I could have missed?

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