Accidentally emptied a Note, which was then automatically deleted I accidentally emptied the content of one of my Notes by selecting all and then pressing on the &quot;return&quot; key - removing everything.
I then quickly exited from my, now empty, Note, which my iPhone 8 automatically deleted.
And since this was an iCloud synced note it promptly synced it over to my Mac and deleted it from there.
So since technically I didn't delete it I can't find it in my &quot;Recently Deleted Files&quot;. And checking my backup data on my iPhone there doesn't seem to be an option for Notes.
I'm sorry to say this but I think your note is permanently deleted.
Here's why: 
Deleting text in a note is like deleting text in a Word-document. When you delete all text in a Word-document, you can still undo (using CMD+Z) while the document is open. If you closed the document, the undo history gets deleted. And I thinks iOS Notes works this way. Try to create a new Note, add some text, go back, exit the app (by swiping up) and open it again. Can you undo(shake the device) to remove text? No. Undo history is gone.
