MBP late 2013 High Sierra unknown partition(ffff...) with suspicious MBR

So I’ve followed a lot of the instructions I was able to find through a lot of similar issues that klanomath has been a mastermind at solving. I got all the way up to figuring out what my actual partition UUID is. But I ran into a ‘suspicious MBR at sector 0’ followed by another ‘no space available on device.’ I started following instructions by klanomath for the MBR problem of destroying and recreating the disk0 however now when I try to create the partitions I get something that looks like terminal instructions on properly executing gpt add command. I’ve looked it over and my parameters appear to be correct so I’m at a lost on what to do here. Really hope I didn’t mess this up, I’ve got a lot of stuff I really don’t wanna lose on my computer. Here are some photos of my terminal.
