What is the Box Category on 1099-B ?
For non-covered securities ( BOX B or E) showing zero (or 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).
Alternatively, in your situation, instead of Code "B" you might use Code "O" (other).
Code "B" is more common.
