You must have answered a question incorrectly. Your original question above says you had "RSU stock sales," not dividends. You must have entered something that made TurboTax think you had foreign dividend income. Go through the interview again. Read the questions very carefully, and make sure you answer each question accurately.
On the Foreign Tax Credit Summary screen, try deleting all of the entries listed, then start the foreign tax credit section over from scratch.
At exactly what point does it ask you to select a 1099-DIV? What is the exact wording of the question or instruction? Can you post a screen shot? (Exclude any personal information. This is a public web site.)
