What is the Box Category you are reporting? see exception below.
If you are not excused by the detail reporting exception,
IRS requires details of your SELL transactions to be supplied on some Form 8949,
or on your other forms (e.g. consolidated 1099-B or spreadsheet) which have the same information and in the same manner as Form 8949.
This is so, even when the broker has sent details to the IRS already.
The exception does not include wash sales, since they have an adjustment.
-----
Detail Reporting Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary. No attachment is necessary.

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).
If you go through the TurboTax dialog, TurboTax will comply. That is, it did in the older versions I tested.
