Turbotax will split income and expenses. If you put 50% of partnership, the income will be divided by 2. The only expenses you will need to provide are for your part only, and for the CCA deduction. On this area, you will need to enter only your % of the amount there.
If TurboTax still does not calculate properly, you can contact TurboTax support using the following link:
