The 1099-B "Needs review" section was infuriating. I had over 1000 transactions and about 8 needed review. They were grouped in sets of 200. But within each section I was presented about 20 transactions and had to manually scroll through to find the ones marked "needs review". If it was there, click to the next set of 20. Also, there is a "trashcan" delete icon to the right of each one that was sometimes cut off from view (Chrome). There was no way to search the transactions; I had to scroll and look manually. Paper would have been easier. Also, the transactions in question turned out to be mis-categorized.
