When I run a Tax Summary report I see some, but not all, of my tax categories. For instance, I have a category for pension federal tax withheld linked to Quicken's predefined "1099-R: Pension federal tax withheld." The Tax Summary report includes all entries correctly.
But I also have a category for IRA federal tax withheld linked to Quicken's predefined "1099-R: IRA federal tax withheld." The Tax Summary report does not show any entries for this category. I think this is an oversight. Or maybe the "oversight" is a deliberate error part of Quicken's philosophy to ignore properly recording transactions related to removing money from IRAs.
