HS transcript for Transfer Student

I’m freaking out, I was so focused on the transfer app and Personal Statement as well as college, I didn’t really think I needed to send in my high school transcript and yeah sounds dumb to wait until the last minute but will this greatly affect my UW application, is there no way I could turn it in after?

** My high schools are back in CA and they need you to request a transcript by filling a form and turning it in person but i’m not sure how I would’ve even done that if I lived here already. Please help and answer, i’m beyond stressed and I would really regret knowing I couldn’t apply just because of a high school transcript.
