Do I file the sale of stocks different based on a gain of a loss on the sale?

[sessions2407]

last year i sold stocks for a net loss. Which forms will i need to fill out to show a deduction on my income? Now I still have yet to receive a 1099B form that i believe I'm supposed to receive from JP Morgan. Will the 1099B show that i took a net loss or does it just show that i received income for the same of the stocks?

So since I sold the stock for less then what i had bought it for, how do i file the money i got form the sale and how do i file the loss on my of the sale?
