@kgrayson -- You don't have to file in DC if you never lived in DC. DC income tax applies only to residents of DC.
If you never lived in DC, but your employer withheld DC taxes, file DC Form D-40B to get those taxes refunded. Here's a link: https://otr.cfo.dc.gov/sites/default/files/dc/sites/otr/publication/attachments/2018%20D-40B.pdf
If CA was your home state prior to your move to VA, and if you moved to VA with the intent of making it your new main home, then for 2019 you are a part-year resident of CA and a part-year resident of VA.
