The rental income is the total amount you receive from all sources for the rental. When you enter the information into the program you will enter under income the total amount you received for the rental. You will also be asked later in the program to enter in all the expenses (including mortgage interest for the property. This will reduce your rental income and properly calculate the profit/loss of the rental.   

To enter in your rental information, please follow the steps below:

1. Login to your TurboTax Account

2. Click Continue your return if you have already started a return. 

3. Click on Go to Federal Taxes heading
