After I file a forgotten w2 from 2016, should I wait to file my 2017 w2 until after I amend the first? Or can I file 2016, then 2017 and send out 1040x in the same day?

I had a 2016 w2 from a prior job come in after I had already filed my 2016 w2 from my current job. Should I wait to file my 2017 w2? Or can I file both in one day and send out the amendment
