Thank you for the question. So these are the resources you should be using from Turbo Tax:
TurboTax's W-4 Calculator
TurboTax's Tax Caster tax calculator
If you have a single W-2 your W-4 should generally cover your taxes. For purposes of this answer, I am assuming that you have other income, which the W-4 calculator will help you account for, in making certain you are withholding enough in taxes during the year.
Be well and safe @gqjason
