Hello andrya288,
Welcome to Apple Support Communities!
If we understand your post correctly, when you mark a task as completed you want it to show completed and not reset for the following day. We'd like to help!
"To mark a reminder as completed, tap the empty circle next to it. To see your completed reminders, tap the More button
, then tap Show Completed.
To delete a reminder without marking it as completed, swipe left on it, then tap Delete.
If you get a reminder notification on your Lock Screen, swipe left over the reminder. Tap View, then tap Mark as Completed."
Use Reminders on your iPhone, iPad, or iPod touch
Let us know if you have any questions.
Thank you for using Apple Support Communities.
Take care!
