Should I amend my 2016 tax return if I made nondeductible contribution to traditional IRA in 2017? If yes, how should I do that?

I have finished my 2016 tax return. However I decided to make nondeductible  contribution to 2016 traditional IRA in 2017. Do I need to amend my 2016 federal and stat return? If yes, how should I do that? Thanks.

Yes. You should amend your federal tax return. For any nondeductible Traditional IRA contributions that you have made or will make between January 1, 2017 and April 18, 2017 that you have designated as 2016 contributions, you would need to amend your federal tax return in order to report your nondeductible contributions on Form 8606.

For the federal return do I need to file both form 1040X and form 8606 or I just need to file form 8606?

From looking at the instructions to form 8606, it looks like you need to file both Form 1040X and form 8606 but the instructions arent clear on it.
