Deductions & credits

After reading through two pages of replies, I finally found the answer I need from your reply!

 

In other words, to answer the "Report Foreign Dividends" TT interview using my 1099-DIV from Vanguard, I should add up all the "Security Total" in Box 1a (total ordinary dividends) with a non zero Box 7 (foreign tax paid) on the same row.

 

Thank you so much!
