Missing w2

I filed my 2019 taxes and got a return. I worked 2 jobs and only got 1 w2 so I only filed the one and got my refund and just remembered I didn’t receive my other one. I’m sure I will end up owing. I have not received anything from the IRS, no letters or anything. What do I do? Let them find the mistake or fix it myself?
