I've had a couple of extension filers get letters informing them of interest and penalties due.

They owed more than $1000 ($500 California), and I discovered that Lacerte does not automatically calculate interest and penalties on late payment unless a "1" is inserted in the fields for Late Return Penalty and Interest on Screen 8.   This is true even if a filing date is entered on Screen 8.

Is there a way to make this the automatic default in Settings?  I know I will occasionally forget to insert these 1's.
