Nursing programs

I need some advice and help please . I want to go back to school . I graduated in 2018 and never went to college all I did was work . Im interested in pursuing a career as an RN . I don’t know where to start though. I want to do classes online I have a full time job and I have a 1 year old so having online school would help a lot . But I don’t know what schools do that or how to even apply . When I do try it says I’m required to have a RN certificate. Which I don’t have . If anyone could mention some schools or programs it would really help
