I made a huge mistake for buying a stock, which has a Schedule K-1 with code 11 C (Section 1256 Contracts and Straddles), only $86 there, but TurboTax considered this as sold investments other than stocks or bonds, TurboTax is wrong, because this is just a stock.
Having Form 6781 is no big deal especially for $86.
Having an amount of $86 is unlikely to trigger an audit on any form.
Changing code from what is reported on your tax documents is probably more of an audit risk.
@yonghai thousands of people invest in these partnerships so they all have this 1256 reporting. I've had such reporting for multiple years and have never had a peep from the IRS. Noone can guarantee you won't be audited but the reason is unlikely to be this. I would say there's a higher probability of you flipping a coin into the air and having land on its edge.
