Thank you for
reaching out on the community and telling us about your issue. Currently there is no way to edit the memorized payee list inside of the mobile app. If you would like to get rid of them you can go to the application on your computer and delete them from the memorized payee list.
For windows open up quicken and across the top click on Tools -> Memorized payee list. Once in the list right click the payee you would like to remove and select delete. Once this is done make sure to update your cloud so that the changes go through.
I would also
recommend looking at our support article Here in for some additional tips and tricks under the delete transactions section to help you keep that memorized payee list clean.
Please let us know
if this helps resolve the issue for you.
