No. All you need to do is enter your w-2 information into TurboTax exactly as it appears on your w-2, under the wages & income section.
If Box 13 was checked for Retirement plan this means that you participated in
your employer's retirement plan during the year. This might be a 401(k) plan,
403(b) plan, SEP-IRA, SIMPLE-IRA, or other type of pension plan. If you
participate in a retirement plan, your ability to deduct contributions to
a traditional
IRA may be limited based on your income.
Your retirement plan contributions were taken
out of your paycheck pre-tax and have already been deducted from your gross
wages in box 1 on your W2, so you will not be taxed on these amounts.
TurboTax will ask you all the appropriate questions for this situation and as long as you enter your w-2 in properly, your retirement contribution amounts have already been handled by TurboTax and any deduction or credit (The Retirement Savings Contribution Credit) you are eligible for is automatically applied after your w-2 form information is properly entered.
Do not enter your contribution amounts elsewhere in TurboTax if they were already included on your w-2 form.
I have attached a Word document that explains every line and box and code on a w-2 form, for a better understanding of what work TurboTax does behind the scenes, when you enter your w-2 information.
