I rent a second home out that I still may a mortgage on; how do I calculate my income from this home?

[Leonard]

To calculate your income or loss from your second home that you rent you will need to use Schedule E to report your income and expenses.  When you have entered all your expenses and income Turbotax will automatically calculate your profit or loss.

You can access Schedule E by entering rental property in the find box then select Jump to rental property in the results box.  follow the program prompts to enter your rental property information.
