You should be creating 2 separate Schedule C's- One for your statutory W-2 income and the other for your 1099's per the IRS code. You will allocate your expenses between the two schedule C's. This is NOT an unusual situation. It is very common for insurance agents/ some financial advisors through certain companies. I am a CPA and the information provided in this link is not clear.
If you have this situation and are not sure what to do, I highly recommend seeking out a CPA or actual accounting professional!
TurboTax may be great for certain things like smaller returns but based on the answers to these questions.... this is out of the scope of their knowledge.
