How and where to enter 1099-B Section "Other Transactions - cost base not reported to IRS - Form8949, (X)

At the end of my 1099-B this "Other Transactions" pops up; however, there is NO section on the Turbo Tax drop down selection that says this - there is only "short/long-term covered or non-covered" or "no 1099B form" as choices.  Where and how do I enter this large list?
