You don't have to enter all the sales individually. You can make summary entries. In TurboTax Premier, after you enter the name of the brokerage, you will get a screen with two choices: "I'll enter one sale at a time" or "I'll enter a summary for each sales category." Select the second option, and it will then give you boxes to enter the total proceeds and total cost, and select the sale category (short-term or long-term, covered or noncovered). After that screen, you will get a screen that asks if you need to enter another sale, meaning totals for another category. You have to enter separate totals for each of the four categories.
If all the sales are "covered," meaning basis was reported to the IRS, that's all you have to do. If some of the sales were noncovered you have to send the IRS a statement listing the individual sales. That statement can be a photocopy of your brokerage statement (or just the part for noncovered sales). If you file your tax return by mail, attach the statement to the return, behind all the IRS forms and schedules. If you e-file, TurboTax will create a Form 8453 for you to print. Attach the statement to Form 8453 and mail it to the IRS promptly after your e-file has been accepted.
