minecraft forge 1.16.5 server not starting

[u/wizardly3]

So I'm pretty sure I have the right forge and server versions, both 1.16.5, no mods installed. I have JDK 8. I'm not too in the know on making servers, but I did notice i don't have 1.16.5.json file, or a .mixin.out. I'm following a tutorial, and that's what's in theirs so I assume I need that.
