You should be able to just navigate back to that 1099-DIV in the Federal section, and edit that 1099-DIV....then choose "Multiple States, from the end of the list of states. Just click on the "Federal Taxes" tab, then the "Wages&Income" sub-selection, then "I'll choose what I work on"...scroll down the 1099-DIV section and you're there.
