Foreign Taxs from investment accounts

I have Foreign Taxes paid on my 1099-DIV from a brokerage account.  Turbo Tax is asking "You entered $xxx.xx of foreign taxes paid.  Now enter the portion of the Now enter the portion of the $xxxx.xx dividends and distributions that was from a foreign country or U.S. possession"? 

 

The "$xxxx.xx dividends" does not match any numbers i can find on my 1099-DIV .... what does that number come from?
