In general, you pay taxes in the state where you live and in the state(s) where you work.
You are correct to be cognizant of domicile. A college student typically is assumed to still be domiciled at his/her parents' home, when away at college.
It sounds like you need to file a resident CT return. You also need to file a non-resident return in VA. TurboTax will see the state code in boxes 15-17, which undoubtedly has VA on it.
It does not sound like you need to file a DC return, since you say you still domiciled in CT, and (I assume) are still working in VA.
Why are you still a resident of CT when you appear to have left home for a job?
