Welcome, @MegAnne_Casey,
Recurring tasks are perfect for things you need to do weekly or biweekly. Only the very next upcoming recurrence exists for the upcoming next date. Upon marking that task complete, if it’s designated as a recurring task, then in a few seconds, the subsequent future next task will appear.
You can read more about the feature here:
There are many features to this too, for example different regular cadences like annually repeating, and custom ones. Or “periodic” which means the next recurrence will appear a certain time after whatever date you happened to complete the last one.
Hope that helps,
Larry
