Depends on the type of IRA. There is no need to amend if it was a Roth IRA. You would only want to amed to report Roth IRA if it would result in a Savers Credit refund.
If a Traditional IRA then it needs to be entered (amended) to either deduct it and get a credit for the deduction or to make it non-deductible and report the basis on a 8606 form.
A Roth IRA contribution does not actually go on a tax return, but you should enter it anyway to:
1) Tell you if your income qualifies you for a contribution and warn you if it does not.
2) Check if your income exceeds the limit to contribute to a Roth.
3) Track your contribution year-to-year if you use TurboTax every year.
4) Add the Retirement Savers Credit if you qualify.
