If that is what you did in 2017 also, then 2017 is correct. You did not indicate that you made a 2017 conversion of the 2016 contribution.
However, your 2018 8606 does not appear to show *any* 2018 conversion at all since the entire 2017 carry-forward basis and the 2018 contribution ($11,000) appear on line 14.
That indicates that if you did have and entered a 2018 1099-R for a 2018 conversion, you failed to complete the 1099-R after the 1099-R summary screen where the questions are asked to enter the basis.
If you failed to check the IRA/SEP/SIMPLE box on the TurboTax 1099-R screen the same thing would happen - that question about basis would never be asked - it is only asked if that box is checked.
