Why do I owe Virginia state taxes while being in the military for a total of 1080.00

[Critter-3]

1) did you indicate in the MY INFO section that you were active duty military ?

2) did you indicate the W-2 was military ?

3) what is your SLR ?       Did you indicate that in the MY INFO section ? 

4) did you work outside of the military ?   Did your spouse if you are married ?

Specifically, why would you not owe taxes to the state of Virginia on your earned military income?
