Follow-up. I persisted by deleting the messed up 1116 form and its worksheet and tried again, using the steps recommended by Julie S. I had tried that yesterday but decided to try again. The dollar numbers that TT automatically placed in the total foreign income received box was not what I had calculated for the brokerage account's tax package 1099-DIV, so I changed that number to reflect the information on the actual brokerage account 1099-DIV itemized table of dividends received, foreign dividends received, and foreign taxes paid for each security that had foreign income. In the form view, there were still a few flags and pink highlights that I eliminated, using my best judgement about what to place either in each pink blank space or edit an already existing entry. All the pink spaces and red flags disappeared. In the end, TT prepared a tax credit that was a little lower than the sum of the foreign taxes paid (per the Box 7 entries) but I'll let the IRS tell me if they disagree. If they do, most likely they'll send me a refund for over payment. Thanks to those who replied!
