Can anyone advise me on how to get a remote job?

I live in the United States of America. Am I open to acquiring any new skills I may need for the job? But I have no idea what jobs to apply to or how. I turned 18 recently, and I have a busy schedule with AICE and Dual Enrollment classes, so I can’t get anything that’s not flexible or online. (Still in high school by the way.) Can you advise me on what works and how to apply for it? Or how to find them?
