No. That should have been reported on your 2015 tax return. If you did not report it then, you do not need to amend, but can file a stand alone 8606 form with the 2015 contribution on line 1. Any prior nondeductible contributions from the last filed 8606 line 14, on line 2. The total of 1 & 2 on line 3 and 14. And mail it to the IRS.
You can download the 2015 8606 form from the IRS here:
