Thanks very much @JohnB5677 - I appreciate the information regarding the statute of limitations.
However there is a complicating issue, at least potentially:
-I made a non-deductible contribution to my Traditional IRA for ty 2016, in addition to doing a Traditional-to-Roth conversion
-I therefore need to file the 8606 for 2016 (which I failed to do at the appropriate time), to notify the IRS of the contribution, so that my basis is properly tracked
-Since I'm filing & signing the 8606, I feel I have to also state that I did the Traditional-to-Roth conversion, and that it had a taxable component (not to mention, the conversion itself impacts my going-forward basis in the Traditional IRA)
In light of all that I see a few potential options; I would appreciate your views on which is best!
1) File the 8606 on its own (signed) w/ $50 late filing penalty
2) File the 8606 with an amendment to my 2016 return, using 1040-X, with additional tax payments related to the taxable component of the conversion
3) Don't file the 8606 and follow some other procedure to keep the IRS informed of my basis in the Traditional IRA
Thank you again!
