If I had a child in 2016 but not claiming her on my taxes should I answer yes or no to having a dependent

[KenH1]

If you don't plan on claiming any child-related credits (dependent, child care credit, earned income credit, child and dependent care credit, head of household status), then answer No.

If you think you might be eligible for these credits (even though you're not claiming her), answer Yes but also answer Yes to "is this child being claimed by someone else"

TurboTax will ask you questions and determine any eligibility.
