Thank you both. I have exactly to a T the situation @andrewmagee laid out in his example. It is pretty odd to me that the firm that issued the 1099-B reported it this way where gain/loss does not reflect their reported proceeds minus cost, but I'm sure there must be some regulation requiring them to report it that way. They explained that it is due to a conversion of short-term capital loss into long-term capital loss in the notes and commented "taxpayers will need to reflect this adjustment when preparing their tax returns." I am wondering if I can fix it through a type T "(type of gain or loss is incorrect)" adjustment on each entry - one for the short term sale and one for the long term. I would only enter the amount that needs to be shifted for each (in my case, we're only talking about $20!)
