How do I account for both a backdoor roth contribution (done in January) and 401k aftertax rollover (done in December) to traditional IRA and roth IRA?

I did a backdoor roth conversion in January 2017 for $5500.  In December 2017 I rolled the aftertax contribution of my work 401k (total amount $16,500) to a roth IRA ($15,000) and a traditional IRA ($1,500). 

I originally received only one 1099-R for the aftertax rollover.  I took the TurboTax advice to split my 1099-R into 2 documents.  One for the Traditional IRA ($1,500) and one for the Roth IRA ($15,000).

Later in the questions, I was asked to state the basis of any Traditional IRA's that were out there (on my form 5498) and I stated the amount that was in my traditional IRA ($1500).

When I look at the actual 8606 form, it shows that I made a non-taxable contribution of only $4000 and a taxable contribution of $1500 when I obviously converted the whole January 2017 contribuiton of $5500 to a roth IRA and there should be not taxes. 

At the end, I should only be liable for taxes on that $1500 in my traditional IRA.

How do I account for all of these inputs correctly?
