You're under the age of 24 on Dec 31 of 2017, so your income "might" not matter here. Here's what does matter.
Were you enrolled as a full time student for any one semester that started in the tax year? (Yes, for sure, and you were a student for 5 months of the tax year too. Even if you graduated on May 1st, the entire month of May counts.)
Did *YOU* (not your parents) provide MORE than 50% of YOUR OWN support for 2017? Scholarships, grants, gifts from Aunt Mary, 1099-Q funds just flat out *do not count* for you providing your own support. Note that there is NO requirements for your parents to provide any support. Not one single penny. The support requirement is all on you, the student.
How many months did you live with your parents? (Note that time spent away from home for the primary purpose of attending school is time considered to have been living with your parents.)
Now on that last question, for you it would be 7 or 8 months you lived at home. Now I'm not 100% positive on this, but I do believe that since you did not "live at home" (by the IRS definition) for the entire year, your parents do not qualify to claim you as a dependent on their tax return.
However to confirm that, when your parent's work through the program (assuming they use TurboTax also) and indicate that you lived with them for less than "the whole year", I would "expect" the program to tell them they can't claim you as a dependent.
