strongly recommend that if you manually input schedule D data, you wait for the 1099B from the broker so you can check the numbers. there can be reasons why your numbers may differ from the broker's form. one common area is return of capital dividend. the brokers are usually not informed of this until after year end. then they go ahead and reduce the basis of that stock increasing gain or decreasing loss. any in that case your numbers and the brokers will not agree.
