Form 1116 -- long-term capital gain distributions

The Foreign Tax Computation Worksheet in Trubotax has a line for qualified dividends and long-term capital gains distributions. Vanguard adn others have percentages used to determine foreign qulaified distributions but do not indicated for their foreign stock mutual funds what percentage of long term capital gains (Box 2a on the 1099) are foreign. Should long-term capital gains be included on the worksheet as reported on the 1099 for this line and in the line for foreign gross income as a separate item from foreign interest adn dividends. Vanguard cannot provide any information about the long-term capital gains distribution.
