This tax year is there a Virginia State return income deduction for paying past Long Term Care (LTC) premiums from 2011 to 2013?

The VA return Turbo Tax software asks if we paid LTC insurance premiums prior to 1 JAN 2014.  We paid 2 x 20 months of premiums (for both of us) in 2011 through 2013 and see that our prior VA returns for those years did not have income deduction for LTC insurance premiums paid.  Called Virginia State Tax advisors (Richmond) who couldn't tell me one way or another if this is the case.  I wanted to confirm this is the rules before I go forward.  I have contacted insurance co to obtain official record of the premiums paid during that time.   If this is a true VA state return deduction, great!  Appreciate the assistance!
