Futures P/L is reported on form 6781. You can just report the aggregate P/L. No need to itemized it. But I'm not a tax lawyer. I believe TurboTax Deluxe has this form too. Standard should have it also. You do not have to go through the interview questioning. You can just get the form and fill in the info.
I believe he meant itemized deductions, as in mortgage interest, etc. But you are correct, form 6781 only asks for the info supplied on your 1099B which is gross profit/loss on those contracts.
I've used the Premier version the last few years for a couple other items I have going on, but in the past I used the Deluxe version, and had no issues, but that could have changed and for some reason you need the Premier version for section 1256's and form 6781. I wouldn't have thought so, but that is a possiblilty.
