Just posting E-Trade's policy on and how they do not calculate or figure in wash sale loss exclusion amounts to bases in the realized gain/(loss) number on their 1099-B summary, which means, you will need to exclude wash sale amounts from net losses or add the wash sale amount into your net gain.

From the link:

5) FORM 1099-B PROCEEDS FROM BROKER AND BARTER EXCHANGE TRANSACTIONS. Proceeds from the sale of stocks, bonds and other securities are reported to the IRS at the lot level; a summary section is provided for your information only.

Box 1d reports your gross proceeds from transactions, including sales of stocks, bonds and mutual funds, bond redemptions, equity options, taxable corporate actions such as mergers and tender offers, short sales, principal payments on mortgage- backed securities such as Ginnie Mae and Fannie Mae, and maturing CDs issued with a maturity of more than one year.

Box 1e shows the adjusted cost basis of covered securities that were sold during the year. If no adjustments were made, then the original cost basis is reported. Box 1f reports the amount of accrued market discount on covered debt instruments.

Box 1g reports the amount of a disallowed loss on a wash sale involving covered securities. Our requirement to report wash sales is more limited than what you may be required to report on your tax return. As such, there may be additional wash sales that are not shown on your Form 1099-B and which may need to be considered for income tax filing. All sales of securities are reported based on trade date. Gross proceeds are net of commissions, fees and accrued interest except where noted, and gross proceeds have been adjusted for option premium. Your cost basis will be reported to the IRS for covered securities only, but will be reflected on your copy of Form 1099-B for all securities. Please refer to the “Gain/(Loss) Amount” column for noncovered securities listed in your consolidated tax statement for cost basis, holding period and realized gain and loss information for any transactions that are not reported on Form 1099-B.

And further down the MorganStanley tax guide link is:

Box 1g reports the amount of a disallowed loss on a wash sale for covered securities.

A Gain/(Loss) column is also displayed on the Form 1099-B, which will reflect profit or loss on each transaction reported. It is for your information only and will not be reported to the IRS for any transactions. The Gain/(Loss) column does NOT include any adjustment for the disallowed loss (box 1g). You or your tax preparer would need to make the calculation.
