I need college advice

I'm trying to get into computer science, specifically software engineering, but I don't know where to start. I just graduated high school and I find myself lost. I live in the suburbs of Chicago and I would rather take classes online or attend a college near me. What exactly would I need? I never really thought about going to college until now so I'm kinda overwhelmed, I just need a sense of direction. Any and all help would be greatly appreciated.
