How would I be able to reset my input settings?

So I found that my keyboard was responding late when it came to hitting notes. So i went to change my global offset (I believe) and now that I think I solved the problem when it came to my keyboard hitting notes late (which was a simple keyboard reset), I need to reset my input (or global offset) back to 0, because the notes would not be aligned with the song (like a technical ■■■ wouldn’t actually be technical). Let me know if I explained this to a understanding state, if not just ask a questions for specifics, and yeah.

On the song select screen: Hold f3 press f8 then press 8. This will reset global offset.

thank you.
