It is somewhat tricky to get to the area to enter your Foreign Source Income.
If your 1099-DIV shows an amount for Foreign Tax Paid, check the box under Box 1b - Qualified Dividends, 'My form has info in more than just these boxes..'. and enter Foreign Tax Paid.
Then in Deductions & Credits, choose Foreign Taxes from the topic listing.
TurboTax asks if you want to take a Deduction or a Credit, then you come to a screen titled 'Where did you receive the Dividend Income From?'
You can select RIC for income income received from a mutual fund (screenshot).
On the next screen, you can indicate that you want to report the Foreign Dividend Income, and link it to your 1099-DIV.
Then you enter the amount of Foreign Source Income (screenshot).
