Your W-4 was given to your employer to tell them how much tax to withhold from your paychecks. It did not go to the IRS. Your W-4 does not dictate how you have to file your tax return. If your filing status is Single, then that is what you use on your tax return. One problem you may have is that less tax is withheld if you say you are HOH on your W-4, so your refund may be less or you might even owe tax due.
If you find that you need to change your withholding for the coming year, prepare a new W-4 for your employer for 2025.

And that stuff about "my parents want to do joined taxes" does not quite make sense here. How your parents are filing their tax return has nothing to do with your own W-4. Why did you mention that?
Are they claiming you as a dependent? If you can be claimed as a dependent by your parents, you must say in MY INFO that someone else can claim you.
