Can someone help me lean out as a teenager

I have tried making a plan with ChatGPT, Gemini, Claude, Perplexity, and other less known AIs to help and they keep bouncing back and forth. ChatGPT says I should not eat in any deficit and build muscle; Gemini keeps going from cut calories to eat at maintance, Perplexity said to cut, and Claude refuses to help. And I also would like to know my maintance. I am 12, 5' 6.5", 119lbs, and boy. Tell me how you got there so I can adjust the numbers as I grow. I work out 4 times a week, and I walk over 14000 steps daily averaging 16000 (Don't ask). Most of the steps is from pure walking. Walking and school are my main activity. I made a routine. Monday and Thursday are Leg Day and Tuesday and Friday are upper body.
Leg day (2 sets of each)
Suitcase Squats
Long Lever smth smth (it's like a glute bridge that hits your hamstrings)
