Retirement tax questions

Contributions you make to a 401-K plan are deducted in the form of a subtraction from your wage income, as reported in box 1 of your W-2 form. So, you pay tax on your net wage income after the contributions are subtracted, which is reported when you enter your W-2 form. There is no additional entry you need to make in TurboTax.
