Entering data for Stock Sales

I have a 1099-B that has data for Box A, Box D and Box E.  Box A & D's cost basis are reported to the IRS by the brokerage firm and I have no adjustments to their numbers -- So I have input the relevant numbers in Summary form and they appear on Schedule D, Line1a (Box A) and Line 2a (Box D).

 

For Box E, the cost basis are not reported to the IRS and I need to input them.  There are only 3 sales for Box E and I would rather input them individually in TurboTax -- as oppose to mailing the Form 8949 separately.

 

How do I enter the individual sales?  Do I have to create a dummy account?
