Hi - I am the original guy who started this thread. I just filed my 2017 taxes, and it prompted me to report the excess earnings, then told me to amend my 2016 taxes. I was trying to avoid this when I realized my excess contribution last year. Anyway, I filed the amendment and it was no big deal. Essentially I had to report the interest income of the excessive contribution as income.
So I'm not any kind of tax expert, but it works for me and was easy. I would just move forward, file your 2017 taxes, and when you file next year, expect to have to amend your 2017 return. I did it with last years Turbo tax program and it was actually very easy.
