Make sure your TurboTax software is up-to-date. In Windows, on the "Online" menu select "Check for Updates." On a Mac, quit and reopen the program to check for updates.
What exactly do you mean by "won't allow"? Do you get the Add Form window shown in the screen shot that I posted above? What happens when you click on the box for the payer's name? Do you get a cursor at the left end of that box?
You said you have existing 1099-DIV forms. How did you get those?
Here's another approach to try. Open one of the existing 1099-DIV forms. At the very top of the form, just below your name, it says "QuickZoom to another copy of Form 1099-DIV Worksheet." Click the QuickZoom button on that line and see if you can add another 1099-DIV that way.
