Amount in 2016 W-2 Box 12 Code W is for HSA contribution made in 2016 for 2015. I had HDHP in 2015 but not in 2016. TurboTax wants me to pay penalty on this contribution.

In the instructions for Form 8889 there is a "Employer Contribution Worksheet" that allows to subtract from the amount reported in 2016 Form W-2 Box 12 Code W employer contributions made in 2016 for the tax year 2015. But I can't find where can perform this calculation in TurboTax.
