I accidentally filed using last year w2

So I made a mistake an accidental used last years w2.. it says accepted and my refund around 1100$, if I would have used the right w2, it would be a refund around 1350$. I’m worried I’ll be audited or won’t get at the very lest the 1100$.. so worried .. I am going to amend my taxes if it gives me the chance, but I am just very very worried
