URGENT, HELP! Fafsa household verification?!?

I know decisions are tomorrow, my FA will definitely be delayed…
I just saw the form in my portal, but the biggest issue is not that. I easily filled it out.

The form asks for an “Student ID Number,” word for word. Can someone please help me figure out WHAT ID number they want?? Is there a JHU ID number somewhere or do they want the FSA ID? Where can I find this ID number??
