My old apartment toilet didn’t actually have a way to disconnect the hose from the bottom of the float mechanism. Like the hose went all the way up into the tank, instead of simply screwing onto the bottom. As far as I could tell, it would require replacing the entire float mechanism (and hose) with a new one, which was more work (and money) than I was willing to put into a toilet that I didn’t even own.
Even searching online for how to disconnect it was unhelpful, because every post basically boiled down to “just unscrew it and it should come loose.” But it very clearly wasn’t going to come loose, because the hose ran all the way up into the center of the mechanism; The screw simply held the mechanism in place. I’ve never seen another one like it before or since, but they 100% do exist.
It was particularly annoying because I was already used to using a bidet. I moved into the new place, and discovered after the move-in that I couldn’t install mine.

That’s EXACTLY what my situation is like
It sounds like you’d have to replace the whole stack, but that’s only about $15-20 at Home Depot.
There should be some sort of threaded seal around the hole on the bottom of the tank where the water flows in, and the hardware all attaches to that.
I’ve never seen anything like your situation, you might need a plumber to sort that out.
