A wash sale occurs when you sell a stock at a loss, and then buy it again within a 30-day period. (Even if you didn't initiate the sale, it can happen when fund shares are sold and then dividends are reinvested less than 30 days later.) The loss is disallowed and added to the basis of the new stock purchased. Look in the detail section of your 1099B to find which sale has the $90 Wash connected to it - that is the page(s) you need to send to the IRS. Put your name and SS# at the top of that page and attach it to Form 8453 (Turbo Tax will have that as part of your return). To be safe, you could attach a copy of the entire 1099B to the 8453.
