Traction control light and flashing brake warning lights turned on, how do I turn them off?

After I had parked my car at work on a slight downhill at work I came home and just as I parked I the traction control light and brake warning lights came on. The brake light is flashing, traction control and oil light is solid.

I had the same issue on my car last year and I tried something I found online, and it fixed the issue. I can’t remember exactly what was done, which is why I am here. But it was pushing the brake pedal an x amount of time and tightening the gas cap.

I tried doing it as close to it as possible, but it isn’t fixing the issue. I am not sure if I am doing it correctly.

Any suggestions as to how it’s done or what could perhaps be the problem would be greatly appreciated.

Thanks a lot. :)
