Use the step-by-step to add or edit your 1099-B
Check the box indicating you have other boxes on your 1099-B to enter, such as Basis.
IRS Says:
"For non-covered securities ( BOX B or E) showing zero (wrong) basis, enter the correct basis yourself.
Use code "B" and put -0- in col (g). "
In prior versions, I found, TurboTax will do that.
