I had the exact similar situation for both foreign interest and dividends. For the interest, I followed the advice of the original poster and put it into misc. income. For dividends, I could not find a solution and called TurboTax. She had no solution and we decided to ignore the FEIN issue and leave dividends in the 1099-DIV section and submit return. You simply click on "file" in the left hand bar and follow the prompts.
It worked!. Seems like you can ignore the "issue message" and file anyway. I checked the return and the dividend amount, ended up in the right place on my 1040. Hope that helps.
