I'm not really a fan of teenagers trying to cut unless they're really heavy, which you're not.
You're not "skinny-fat," you're just untrained. It's easily remedied.
I would try to get out of the mindset of thinking about thinks like maintenance level calories or any of those constraining things, and just try and eat good, nutritious foods with a decent serving of protein several times a day.
Your body is still growing, and reducing calories'll starve it of the nutrients it needs to do so. Just try as healthy as you can and train hard. The physique will follow.
