Because I completed a conversion and not a recharacterization, it seems that I should have reported my 2018 contributions as Traditional contributions and filled out form 8606. I did not do this. My tax liability should not change as I did not receive a deduction (since I claimed it as a Roth contribution). Do I need to amend my 2018 return to change this from a Roth contribution in 2018 to a Traditional non-deductible contribution (with form 8606) in 2018?
If the 2018 Traditional IRA contribution was NOT deducted and was a non-deductible contribution then in order to apply that "basis" to the 2019 conversion, you must file a 2018 8606 for with the non-deductible contribution on line 1,3 and 14.
If there is no other reason to amend 2018 then you can mail the 8606 by itself.
