My first unemployment payment still has not arrived - 21 weeks in

I was laid off as an IT help-desk technician and filed right away, and I have been certifying every week. I worked as an IT help-desk technician before this. I answered every question and uploaded my final pay stub. What would you check first?

Mine took about 21 weeks because of an identity check I did not notice. Look for a message or a letter you may have missed in your online account.
