My first unemployment payment still has not arrived after 10 years as a line cook

I filed my claim 20 weeks ago after being let go as a line cook. There are 10 people counting on me, so I am trying to be careful. The page shows my claim as open but no payment date. Is there a step I could have missed?

When I finally got through, the agent said my employer had responded late. Once that cleared, back pay came in one payment.
