Cut,bulk or body recomp

I am 18 years old , 1.75 and 67kg. For the last 1 year i worked out at home and build an okay upper body physique with some muscle. Even though my upper body isnt bad my lower body and especially my butt and thighs are really big compared to my upper. They are really fatty and i used to skip leg days at home because i heard it makes ot worse. I think it happened because i used to play football for 7-8 years without any upper nody training. I want to achieve a lean physique ( my upper body already is lean ) but i want to achieve thatto my lower body too . I plank to go to the gym in 5-6 months
