I lost notes no where to be found

Did you recently delete an email account? If the notes were associated with that deleted/removed email account then they were deleted as well.

Do you use iCloud for Notes? If yes, then you can follow the instructions in this guide published by Apple 👉 Delete and recover notes on iCloud.com - Apple Support
