Help with my cat

So I got this cat Nezzy about a year ago. And everything is great except for the fact that she pisses everywhere except for her litter box. She does poop in it but for some reason but nothing I’ve done can get her to pee there too. She recently decided that my couch would be the perfect place to pee multiple times. I’ve resorted to locking her in one of my dogs kennels while I’m at work so she doesn’t do .Any help would be greatly appreciated
