you probably did what may others do when they sell a PTP and that is to NOT attach the section 751 statement (would require mailing your return), If the IRS inquires you can explain the situation. It was a sale of a PTP. The broker reported the incorrect tax basis using type A or D when for a PTP the correct type is B or D. - tax basis not reported to IRS because the broker doesn't know it. The tax basis comes from the sales schedule provided by the partnership. A copy of which is enclosed. I made a mistake by adjusting the reported tax basis rather than using the adjustment column (code b) but the reported gain/loss is correct.
perhaps also complain to the broker about their misreporting. maybe even move your account.
