Part of the distribution is taxed...the earnings part. Only the distributed earnings are subject to the penalty.
Do you mean did TurboTax take care of it on the original 2015 return? Look on lines 59 or 62 of the 2015 1040. If no entries there, then the additional 10% tax on non-qualified distribution was not paid. Which maybe then also wasn't included in taxable income.
Look at lines 15, 16, and 21 for any entries and what they might be. If blank, then it probably wasn't included in income.
