Am I over feeding my cat

I have a cat and I give her a can of wet food (3oz) in the morning around 7ish and then when I get home from work at 8-9ish I give her a scoop of dry food (roughly 3/4th cup). I just moved out into my first apartment and got a cat. Growing up I always had at least 2 or 3 cats in the house at all time so I’m used to feeding a few of them not just the one. I’m worried I’m over feeding her. I really don’t want her to be unhealthy at my own fault. It just feels like I’m giving her too much dry food but I don’t wanna start feeding her less if she needs more.

She was also just neutered on the 13 days ago while in late pregnancy (she’s a shelter kitty) so the scar is still a little fresh and I don’t know if that matters for her diet or not but I thought I would mention that too in case.
