My prev employer provided incorrect W2’s to all employees. They are sending corrected W2’s now. What do I do if I already filed my taxes with that incorrect W2?

I do not understand the whole situation. However, my previous employer that I worked for in 2023 had W2’s processed by an outside company and subsequently found they were all processed incorrectly (?) I do not know what type of flaws the W2 had. It seemed normal to me. We were told that all W2’s are being corrected and sent out again. I have yet to receive a new W2, but I already filed my taxes with the “incorrect” W2. What do I do now?
