I have a taxable Brokerage account with Vanguard.
I received a Consolidated Form 1099 from Vanguard Brokerage.
Where to find information to answer the following question during TT interview:
"You reported $xxx total income from Vanguard Brokerage. How much of this income was from foreign countries?"
It seems that Consolidated Form 1099 contains information about Foreign Taxes paid, but not about what portion of the income is from foreign countries.
