To change the account associated with a scheduled transaction, you will need to go to the Scheduled Transactions screen – click on “Configuration” in the bottom left corner of the window and choose “Payees, Schedules & Rules”, then click on the words “Scheduled Transactions” near the top of the window. From there, locate the scheduled transaction you want to change, then click on the date that appears in the far right column. This will open a popup window and you will see the option to choose a different account and date for the scheduled transaction at the top.
