No, if your Form 8606 isn't correct then you will have to file a correct Form 8606 for prior years. If you didn't have any earnings when you converted the funds and it will not affect the rest of the tax return then you are able to only file Form 8606 to correct each year. Please see Form 8606 and Instructions.
"If you aren’t required to file an income tax return but are required to file Form 8606, sign Form 8606 and send it to the IRS at the same time and place you would otherwise file Form 1040, 1040-SR, or 1040-NR. Be sure to include your address on page 1 of the form and your signature and the date on page 2 of the form." (IRS)
Please be aware, if you make a contribution in 2017 for 2016 and 2017 and then convert the amount in 2017 then your Form 8606 will have an amount of $5,500 in line 2 because you have the basis from the 2016 contribution.
