Ctrl + Z Manual Status Selection
The Manual Status Selection
The menu for the Manual Status Selection can be accessed from within a return by using Ctrl + Z.
Using this feature will overwrite the current status of the return with whatever you select, and the menu defaults to S Suspended from Further Processing.

You are able to remove the Manual Status Selection on the Information and Status page of the return by clearing the status indicator in the override field.
