Form K-1 for Business? If there is" lose ' , should related to your business income , should not be related to capital(gain/lose);check the instruction for form K-1. Turbotax... should use the small business version. If you report your capital(gain/lose) and pay tax quarterlly by small business way, maybe can calculate them together.
All these belong to capital class or the same income source( if by small business), should can calculate together. But, it related to your report way of income.
Your 1099B from broker must have the UCO sell record reported either as Type A or Type B. That is your real gain or loss on trading UCO. The #11 other income (loss) reported on Schedule K-1 (form 1065) are usually pass-through income (loss), which are reported on form 6781 (for code C) however. They must have provided you with "Cumulative Adjustment To Tax Basis" for each units disposed along with your schedule K-1. You will use these numbers to adjust your cost in schedule-D when you report those trades to avoid double taxing.
I don't use TurboTax. But I read from the web that it will ask you questions when you add the schedule K-1 form, and help you prepare the tax.
