Question about maintenance

I posted here less than a week ago asking for advice about not losing my last few pounds. I was really frustrated and you guys made me change my attitude about the actual number on the scale and try to be fine with things as they are. I did. I realized 4 lbs wasn’t worth destroying my mind so I considered myself done and gave myself a high five. I started eating 1500 kcal again. That’s what I’ve been averaging and maintaining/plateauing since December, but today the scale gave me my goal weight. It’s absolutely not logic. Bodies are weird 🤷🏻‍♀️

So now I have a new question. Should I upper my intake from 1500 kcal or should I keep it there for maintaining? I mean, I was maintaining my weight there for almost 3 months. I’m 5’4 (165 cm) 120 lbs (55 kg) female 47.
