There are a couple of very good calculators you can use to estimate your needed withholding. You'll simply need to know what your filing status will be, the number of dependents you'll claim, your expected income, any deductions, and a few other factors.
TurboTax has a W-4 Calculator that will help you calculate your withholding for tax year 2023.
The IRS, also, has a very useful Tax Withholding Estimator.
And, finally, you can use the TurboTax program, itself. See the TurboTax Help article How do I update my 2023 withholdings and print a new W-4? for more information.
