I created a new list today and lost my old one

I created a new list today by duplicating my original list (SCS FILES) because I wanted to keep the same format. I named the duplicate list MEL’S CLIENTS. After deleting all the info that was carried over to Mel’s list from the original SCS list, I went back and discovered all the data was deleted from my original SCS FILES list. I need that back!! But the most recent “Previous version” is back in the beginning of October. I need my original SCS files list restored to where it was before the new list was created. Please help me!!

Nevermind… got it
