I need to report profit/loss from an investment in a new business. The income form I have from them is 1099-DIV. [removed]

You can enter the 1099-DIV using these steps:

1. Click on Federal Taxes > Wages & Income. 
2. Scroll down to the Interest and Dividends section and click on the Start/Revisit box next to Dividends on 1099-DIV.
3. Answer Yes to Did you receive any dividend income?
4. On the next screen, click on I'll type it in myself.
5. Enter the dividend information. 
6. If you have information in boxes other than 1a, 1b and 2a, mark the box My form has info in more than just these boxes (this is uncommon) and the other boxes will appear.
7. Continue through the interview.
