Based on the NIIT documentation, it is 3.8% of investment income, turbotax seems to get a smaller number and it is only based on 1099-INT and not 1099-DIV. Why is that?

Under Income, I see investments and savings total to be $5360. However the NIIT is 177, which is less than 3.8% of total. I am curious on how Turbotax is calculating this. Was there an unknown deduction or only 1099-INT is factored in?
