When you are entering income on a joint return, every income entry screen will either have a spot with both spouse’s names there, or when you click to enter a W-2, 1099R, etc. it will ask you by name which spouse it is for. You do not have to wait for the software to “ask” you for your spouse’s income. Go to the screens to enter your spouse’s W-2’s, 1099’s, etc. just like you did for your own income. Then look for your spouse’s name there.
If she is a sole proprietor she has self-employment income.
If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare, you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
