There was a tax liability payment in my "pay scheduled liabilities" list.  The amount was incorrect (too high) because a wc rate had not been changed.   When I paid the liability, I changed the amount of the check to the correct amount so the remaining amount is still listed in "pay scheduled liabilities".   I went to "related payment activities" and made an adjustment to that tax liability but the line item in "pay scheduled liabilities" did not go away.   How can I delete it?
