401k paycheck transfer

The "expense" is in the paycheck account, not the 401k account. But removing accounts from reports/graphs is usually not the way to remove "transfers" from reports/graphs.

In a regular report (accessed from the "Reports" menu), you generally have the Advanced tab in the Customize dialog where you can eliminate all transfers. That tab is usually not present for the customization of reports/graphs in the various Quicken "Centers".

If you want some transfers in the report/graph but not others, you eliminate them on the "Categories" tab in the Customize dialog: at the end of the list of categories, are what I call "account categories", account names that appear in square brackets in the category fields of "transfer" transactions (every Quicken "account" is also a "category"). Exclude your transfers by excluding the appropriate "account categories".
