If Traditional IRA contribution and you already reported it, then you must amend to remove it and pay any tax difference if you had deducted it or file a new 8606 if it was a non-deductible contribution to remove it.
If a Roth contribution, then unless it qualified you for the Savers Credit (8880 form), nothing about a Roth contribution is reported on a tax return so nothing need to be done.
