E-Trade should send you a 1099-B. It may be on its way. Check with them to be sure. All brokers are required to do that. See below from IRS. The "proceeds" in this case are the proceeds from the sale of the stock.

"Brokers and barter exchanges must report proceeds from (and in some cases, basis for) transactions to you and the IRS on Form 1099-B. Reporting is also required when your broker knows or has reason to know that a corporation in which you own stock has had a reportable change in control or capital structure."
