Negative investment income

I have inputted investment income of 4630.59 BUT my Turbotax shows Negative -4791.00 for investment income. why is this? I have a capitol loss of 10094.07 so if I deduct 3000 from 4630.59 I get plus 1630.59. Seems like I'm getting more of a deduction than I expected. I think  Turbotax is correct but how is this calculated?

Thanks!
