I am not sure if I paid for more than half of my living expenses with earned income to answer yes or no on the question "Did you support yourself in 2016?"
Background: I am 22 year old who graduated college in May 2016 and began working full-time as a teacher in fall 2016, only receiving a little less than half of my full time salary for the 2016-2017 school year at eoy 2016. Prior to that, I worked two part time jobs. I have lived at home with my parents all of 2016, paying no rent. The only expenses I have paid for are car-related, and now, as of the end of year, student loans and healthcare now that I have my own insurance.
I will not be claimed as a dependent on my parent's return as I have an HSA with my new job and therefore no longer qualify. Otherwise, I would have met the eligibility to claimed as a dependent in 2016.
