NO. IRAs are not the same as a 401k. You do contribute to a 401k through your employer and you would see the amount in Box 12 of your W-2. Once you enter your W-2, you don't need to do anything else.
If you wish to make a contribution to either a Traditional or Roth IRA apart from what you contribute at work, you would enter the contribution amount under the Deductions and Credits section.
