Because it was painful to enter my RSU's sales one by one, I put a section totals for one sales categories (instead of each individual sale) from one of my brokers. Turbotax directed me to mail 8949 and suggested mailing the broker's documents. But it was not clear to only send this 8949 and broker's document related to the RSU's from this broker. Or do I need to mail all my other 8949's and other brokers' statements? I don't want to send the IRS too many documents to confuse the agent and delay my return.
Only mail the brokerage statement that contains the details of the sales for which you entered category totals. Do not mail brokerage statements for sales that you entered individually. Do not mail copies of the 8949 forms that are included in your tax return. The IRS already has those. What you are required to mail is a Form 8949 that lists each sale individually, or an equivalent statement. The brokerage statement is the equivalent statement.
