How to fill out a W4 if you are paid by more than one company, about TAX RETURN, about overtime

Hello.

I have been paid by several companies over the past few years, but I have not been able to fill out my W4 properly and have had to pay a lot of money on my TAX RETURN.
Also, after tax return, I wanted to make the payment as soon as possible, but the payment method was not clear and I could not make the payment by the due date, so I ended up paying a penalty and late fee.

If anyone can help me with the following information, it would be greatly appreciated.
