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).
For Box A or D, leave basis as reported, use Code "B" and put an adjustment in col(g).

I tried this out in an older version of TurboTax, and it complied.
