Not necessarily, as the initial IRS "review" might just be a computer-generated review of attempting to tie out what was reported to them versus what you are reporting. I would not suggest you alter the 1099 in any way, but what you could do is report it on a Schedule C (or "other income", depending on which one is more favorable to you given the rest of your tax situation) and offset the "gain" they have reported with the fees you incurred - and throw in a portion of your internet bill, too, as you use that computer to trade online, after all! Again, which ever scenario (Sched C 1099 income with expenses to offset or "other income" left alone) winds up giving you the more favorable outcome after the system completes your calculations for everything you enter for your tax return.
