Form 8606 - how to get line 1 filled on Turbo Tax?

I funding a Roth IRA in 2016 using the backdoor method of contributing to a traditional IRA than converting the entire amount to the Roth. I've never deducted anything from the Traditional and the balance is $0 a year end 2016..

How can I use the software to trigger line 1 of Form 8606? Turbotax just asks me the Basis (which should be $0) and the value at year end 2016 (also $0). Without line 1 entered as $5,500 it thinks the distribution of the same value is fully taxable.
