Why is Turbo Tax giving a different total long term capital gain figure than what my brokerage firm reported on the 1099-B? It's $3100 higher than the 1099-B.

I only received one 1099-B form, which is all I should have received. I can't find anywhere on the 1099-B the figure that Turbo Tax has generated.

Capital Gains can come from several places. From your sales and 1099 DIV box 2a and maybe a K-1 you got. Or maybe you need to add the cost basis for some sales. If you imported the 1099B it may be missing some info.

Thanks for your quick response! I'm wondering if I need to connect with the brokerage company to question their math. I just have a basic knowledge of taxes and don't do anything out of the ordinary (for me), like selling land or doing investing on my own. I only have the one 1099-B form from the brokerage company to look at and use its figures to complete the investment portion of my taxes. I thought everything should be contained in that 1099-B I received. So I don't understand how the long term capital gains number would jump $3100 in Turbo Tax from what's reported on the 1099-B. I hope this makes sense!
