Virginia state taxes, not giving me credit for taxes withheld in my military retirement. Can't update, help?

While doing my Virginia State taxes on Turbotax Deluxe, I noticed that my "total" taxes paid didn't include any of the money that was withheld from my military retirement pay during the year.  There is no way for me to add this in.  What do I do?  It says I owe way more than I should.
