Good news for everyone: I have a large account with Ameritrade so I have a private client broker working with me. He reported this problem to their tax department. It turned out this is a widespread problem. Ameritrade’s tax department firmly believes this is a TT error. TT misinterpreted IRS’s guidance. They are talking to TT to have it fixed. I don’t know when this will be fixed by TT though. I am a little upset by some folks on this forum that carries a label “employee tax expert” who were stating that “IRS no longer accepts negative proceeds...”. Everyone makes mistakes or misinterprets things. But if have you be sure or cite the sources if you carry a label of “employee”
