How do I fix my wrist going to the right when shooting

Hey, I’m a 13 year old shooting guard from Sydney, AU. My strength are catch and shoot set shot threes and floaters. My weaknesses are playmaking under pressure and hesitating to shoot the ball or make a quick pass. I also can’t translate things from pickup into games very well because I was self taught and never got to play a full court game once in my life confidently.
