If you're a W-2 employee, a non-resident of California, and you do not and will not physically work in California, then ask your company to cease withholding California income tax. Your earnings are not subject to taxation by CA.
If your employer does withhold CA income tax despite your request, at year's end you'll have to file a non-resident CA tax return on which you allocate zero income to CA. CA will then refund the incorrectly withheld taxes.
If your employer cannot or will not withhold VA income taxes for you, you should begin making quarterly estimated tax payments to VA. This reference explains the process:
