how to correct line 13 in schedule D

Line 13 for capital gains?  That comes from any 1099-Div or K-1 forms.  You have to find those to correct it.  

i have two cap gain distributions.  in my tax filing the amount was correct, that is the sum of the two.  after i upgraded turbotax software the number changed.  its no  longer the sum of the two distribution.  i cant seem to correct it.

Better call in for that.
