The contributions were made in Jan 2019 for the year 2019. 

I am using the software version of turbotax. 

The closest thing I see for nondeductibe is a question stating :

Any nondeductible contributions to [person]'s IRA? 

Its asking for non deductible contribuitons made in 2018 or earlier. 

In my case, I perform these steps of putting taxed money into Traditional and then converting the entire amount to Roth. So, I think my basis for 2018 should then be 0?

Did you enter the contribution as I posted above?   The last screen in the IRA contribution interview will tell you if the contribution is allowed and ho much, if any, is deductible.    It should say that your $6,000 contribution has a zero deduction if entered correctly and there should be a 8606 form as part of the tax return with the 2019 $6,000 contribution on line 1.

This is what you should see - the "choose not to deduct" screen will not appear if your MAGI prohibits a deduction , then non-deductible is automatic.

This worked. 

I was not looking into the deductions tab. Thanks a ton!
