Where on my tax return do i report money that was repaid to me with interest from what I loaned to a family member?

You should report the interest income in the same manner as interest received from a bank, just AS IF you have received a form 1099-INT.  Enter your individual’s name as a Payer's name and the amount of interest received in box 1.

In TurboTax, open your return and follow these steps:

• Click on Federal in the left-hand column, then on Wages and Income on top of the screen
• Scroll down to All Income, locate the Interest and Dividends section
• Click Show more and click Start next to Interest on 1099-INT
