How can I find my accumulated data?

Hello. I didn’t click any ‘delete’ button, but my document which has accumulated over a couple of years has been deleted. There is that document, but I can’t find any data there… I tried to check ‘version history’ but I don’t have that function in the document.

Please help me to find my data which is so important for me. The document name is ‘to-do list’, and it has all history of my work.
