Want to make sure I can use the Live/Self-employed option if I have an s-corp? I am really clueless when it comes to how I'm supposed to be doing my taxes!?

M previous accountant wasn't very helpful and I haven't been doing quarterly payments or anything. Plus she registered me as an s-corp when I don't think that was the best option. I haven't been paying myself on payroll and I'm nervous of what the consequences might be! I need help!
