Well, it would have helped if I READ the instructions! Hah! I assumed I had to put "0 Months" when asked "How long has the child lived with you in 2016" since she was born late December. Apparently, both Turbotax and the IRS inform you to input "The Whole Year" or "12 Months" if the child was born any day in 2016, even late-in-the-year birthdays.
