Foreign Taxes

I have 3 items of foreign taxes paid. Two are from two separate brokerage firms and one is from a K-1. The total is over $300 and I would like to itemize them on form 1116. When I go to enter, there are only two line items available. Do I add the two from each brokerage firm to enter one line item? Also, I already entered them on the 1099-Div and K-1 sections of the Turbo Tax walk through. Do I delete those and how can I get all three items in the Form 1116. I was using the walk through feature.
