I have 2 W2s from the same employer both have the same EIN but different control numbers and very largely different amounts listed. Do I file both? HR hasnt got back yet

Does the second say “corrected”?  Did you get them at the same time?

I got both at the same time. I had to get them from ADP website. none of them say corrected. Same EIN but the control number is different and the amounts are very different. 

It is likely that the two forms represent your income from your old and new company owners. If the sum of the two forms is what you would expect as your annual salary then just report both. If not, wait for an explanation from your company.
