How do I move out of my parents house?

Here I am using my sisters account again because my parents don't allow me to have any accounts. (Why my age is 21) I am 16 years old and I am soooooo tired of my mom and brothers manipulative, toxic, lazy, and gaslighting nature. I want to move out as soon as possible. I’m trying to start now so I can be ready by hopefully 19. How do I start getting ready to move out? I live in Tampa and plan to move to Cincinnati near my Aunt, cousins, and closest friends.

To update this question, for those who may assume I am immature because my parents don't allow me to have social media. That is not true. My parents are odd people. I am a very independent and ambitious person. I want to set myself right so when I move out there is no way I will need to move back because of financial issues or something like that. I have done my bills so I know how much I need. I just want to know how to set myself up right.
