My return was rejected per "IND-516". I claimed myself as an exception, but my dad put me as a dependent on his return. Should I exempt or retain dependent status?

I'm 25, my dad put me as dependent as I live at home & parents covered more than half of expenses for most of the year, but I was not a full time student in 2017; I started working in the last 2 months of 2017 and made under $4000. Should he have claimed me as dependent? If not, should I mail my return as it keeps getting rejected here?
