P.S. I find that some USD withholding taxes are reported in different ways in monthly statements. Most are net of withholding taxes (most common) and a few others show gross dividends and then a separate line item for the 15% withholding tax. Doesn't really matter to me.
Added later: I decided to just take the fime and file a complaint via MyLink on this issue. Explained that someone else had gone through this extensively with BMO IL and either BMO IL needs to fix their programming or stop reporting "Income You Received" entirely on monthly account statements.
