To be considered a "full-time student", your Daughter would have to have been enrolled full-time in school during any part of at least five calendar months during 2017. So unless she was a High School student for at least two months of the year in addition to the program she started in October, then she would not qualify as a "full-time student".
Even though your Daughter may not meet the definition of "full-time student", you may still be eligible to claim her as a Dependent on your Tax Return. Please review the qualifications for claiming someone as a Dependent in the TurboTax FAQ below:

Probably not, if over age 18, since the IRS goes by tax calendar years, not academic semesters.
Per the IRS:
Student defined.
To qualify as a student, your child must be, during some part of each of any 5 calendar months during the calendar year:
The 5 calendar months need not be consecutive.
A full-time student is a student who is enrolled for the number of hours or courses the school considers to be full-time attendance.
School defined.
A school can be an elementary school, junior or senior high school, college, university, or technical, trade, or mechanical school. However, on-the-job training courses, correspondence schools, and schools offering courses only through the Internet don't count as schools for the EIC.
