Please explain a bit more. Did you work and receive income in NJ during 2019? Or is that just where you went to school--and perhaps where your parents/family live? You did not say why you are going to NJ on weekends.
And why are you keeping your W-4 with your employer "as NJ?" If you did not live or work in NJ in 2019 then you have no reason to have the employer withhold NJ state income tax. If you lived and/or worked in NJ during 2019 then you might need to prepare a part-year NJ tax return for 2019.
If you did not work or live in N J, then you should be having tax withheld for DC. Then you will file a tax return for your non-resident state first (DC) for 2019 and a return for VA next.
We need more information from you. We do not understand what NJ has to do with all of it.
