Did you begin your joint return correctly so that your income can go under both names?
When you entered your own information in Personal Info, you would have to answer the question "Were you married?" If you clicked the button for Married, then a drop down would appear that asks, "Do you want to file this return together with your spouse?" Then you choose yes to file a joint return. You would then enter your spouse's information into Personal Info. Whenever you are entering income information there should then be a spot for you and for your spouse's income information.
