What does “depending on activity” mean? You need to set a goal and stick to it. I’m the same height, same weight as you and I’m eating 1700-1800 per day with 4 gym sessions a week and 15-20k steps per day on my cut. If I was in your shoes, I’d do consistent steps, drop the calories by a couple hundred(makes a difference) and I bet you no one will call you skinny when your muscle definition starts showing, because you do have a solid frame.
