You mean your W-4--not your W-2. Your W-4 is the form you fill out for your employer so they know how much tax you want to have withheld from your paycheck. You can fill out a W-4 that will change how much they are withholding, but there is not much of 2020 left in which a change will have a big effect. If you expect to owe at least $1000 to the IRS at tax time you could also make an estimated payment ahead of time on the IRS site to avoid an underpayment penalty on your tax return.
