She is considered a resident of CT until she take positive steps to establish a domicile elsewhere. As you note, these positive steps are things like a drivers license, voters registration, owning a home, and where you tell people your mailing address is.
As you can see, there is no single test for domicile, but it is the preponderance of items.
So, she has two W-2s, right? One has a box 15 with a reference to DC and the other with a reference to VA, right? This will trigger the two non-resident returns for DC and VA in TurboTax.
But she will also have to file a CT return, this will be triggered by stating that her residence is in CT in the Personal Info.
In TurboTax, enter the non-resident state(s) first, then the resident state. The taxes paid in DC and VA will become a credit on her CT return. See line 7 on the CT-1040. This is typical of how states deal with double taxation on the same income - they let one state tax the income and let other states create a credit for the taxes paid.
