A blog, "The Finance Buff" did a detailed comparison between TurboTax and H&R Block with respect to how they handle the foreign tax credit. you might find it useful.

One observation he makes is:
"TurboTax is more integrated with the 1099-DIV’s you already entered. H&R Block asks you to add up the foreign tax numbers yourself. Because you have to add up the foreign income anyway, you can add up the foreign tax numbers at the same time. H&R Block software also asks a number of questions that don’t apply to our simple scenario. It’s easy to click through those once you know they don’t apply."
