How do i enter my IRA retirement contributions?

[ThomasM]

If you made Traditional IRA or Roth IRA contributions, click on the Federal Taxes tab, then Deductions & Credits, then scroll down to Retirement and Investments and select Traditional & Roth IRA Contributions.  Follow the prompts to make your entries.

Roth IRA contributions are not deductible, but they are still taken into account for the Retirement Saver's Credit.
