I am trying to deploy to dev and get this error

dev-notes-StorageStack: dev-notes-Notes already exists in stack arn:aws:cloudformation:us-east-1:168458715623:stack/dev-notes-storage/8c33eb70-33db-11ec-8990-0e40bd8a36fb

How do I remove or overwrite it?

This tends to happen when you change the ID of something, and tends to be fixed by deleting the stack and re-creating it.
