Deductions & credits

My 1099DIV from Vanguard did not include any of this information and the website does not give a ratio for the funds.   Several funds on my 1099 DIV had dividends and 3 of those had foreign tax associated.  I took the "total dividends & distributions" I received from each of those 3 funds, added them together, and plan to use that as the total foreign dividend income.  Comments /feedback welcome.
