Where do i enter interest income earned from savings accounts of overseas banks?

Any income or interest received from an overseas bank would be considered foreign income and treated as such. When first creating your return, under the profile section of your return you will have to check off that you have foreign income. It is then under the income section that you will fill in your foreign income information on a page called "Your Name Foreign slip". If you'd like to know more about foreign income and tax treaties here is a link to a great TurboTax article.
