Idiot O1 PPM question

I'm an O1 wrapping up my initial career field training. I commissioned in May 2023 and PCSed to my current location in fall 2023 via a PPM (just my car and a small trailer).

During my in-processing, I submitted my weight tickets, receipts, etc to the civilian team who helped us on board and I believe they submitted them to the appropriate transportation/finance offices.

In the middle of this process, I had a pretty significant family emergency/COVID (and subsequent quarantine period) that literally isolated me from the rest of the process. By the time I got back into class, they'd wrapped up in-processing and I threw myself into training trying to catch up. It wasn't until I was talking to a new O1 today that I realized I had never finished my PPM process. I logged into DPS and sure enough I can see a DD2278 with the message "Shipment status 1: PPM awaiting close out."

I'm kicking myself for letting something so important slip through the cracks. Obviously, I'm way past the normal 45 day window (a couple weeks away from a year). Is there any chance I can still get the reimbursement/payment or am I out of luck? If there is a chance, what should my next steps be or people to talk to? Thanks for your help and apologies for my lack of knowledge on how these things all work-all I know right now are schoolhouse rules which are very much not normal to the rest of the force.
