If you moved out of VA in 2018, then you would file a part-year resident 2018 VA tax return. You were a VA resident until the day you began living in your new permanent home in WA. Your income prior to that date is fully taxable by VA.
As stated before, there is no WA return to file, since WA has no income tax.
