Foreign Source Income

I have foreign tax paid on various Schwab accounts (i.e. small company, International, etc). In the 1099s, they list out the individual countries, foreign tax paid and dividends received.

Box 7 list total foreign tax paid and Box 8 lists various for sources. I listed all the countries, then for each country, TurboTax notes I reported box 1a total income and asks how much of this income was from foreign countries? TurboTax then list “foreign source income” that was prefilled with the total foreign tax paid for all countries of the account.  Shouldn’t this have the dividend income for the individual country and not the foreign tax paid?  Unlike Vanguard, Schwab does not provide any additional info for source details.
