How does final pay work for entry level separation?

Hi all, so I got an EPTS Chapter 5-10 at basic and just got home on the 23rd. I was wondering how the final pay works? I’m aware that I think I’m supposed(?) to get one more paycheck and back pay, but the drills at RHU just skipped over the finance briefing for us so I am not aware as to how it works. Also aware there’s a gov shutdown so I’m not expecting pay anytime soon. Hope someone here can explain, thanks.
