I haven't started my taxes this year but it's sad to hear this bug has not been fixed. I didn't snail mail my Form 8453 to the IRS last year, and they never contacted me about it. I figured the brokerage sends the same 1099 information to the IRS, and the information isn't going to change the tax due, so if TurboTax really didn't send the file I just took my chances that the IRS wouldn't bother me about it.
