A joint return does combine all of your income. You need your own W-2's or 1099's in order to separate incomes by individual spouse. TurboTax does not have copies of those.....you are supposed to save those yourself. But the worksheets that are part of the pdf of your return will have the information...you just have to dig deeper for it.
