Are you talking about your 2023 W-2? And your 2023 tax return? Or are you talking about the 2024 return you will file next year? The IRS knows people get married and change their names. Your Social Security number is the same, right? You have to contact Social Security if you got married, and have SS change the name on your SS card. Your SS number will be the same. And...people move all the time---that is not news to the IRS. When you prepare your tax return, use the information that is accurate.
As for next year----your employer will need to change your last name on next year's W-2, and use your correct address. You will enter your correct mailing address, correct filing status, etc. on your own tax return. You say you "just got married" so presumably next year you will file a joint return with your spouse.
As for your W-4----the document you give to the employer to tell them how much tax to withhold---you can give the employer a new W-4. Hopefully you were never claiming to be "exempt" from taxes since that would have been wrong.
