Thank you for replying. After several attempts, I deleted the 1099-div table and found that other entries (1099-Int, capital gains) summed up correctly. So, I manually imported the 1099-div. Everything looks good.
(Afterward, I tried to find the cause of the problem by re-importing the 1099-div PDF file and compared the outcomes with my manually imported numbers. All entries looked identical. However, TurboTax (online) kept dropping 1099-div data from the final summation when the PDF file is used. Still puzzled).
