My return has already been accepted. Is there a way to check what w2 information was sent to see if it was incorrect?

In addition to the  Forms that are sent to the IRS electronically, when you print your return their will be a number of informational schedules.  One of those is W-2 information.  If you print your entire return (I suggest you print as a pdf), you can then review the details of what W-2 was included in your return.

Thank you for your help. I did print it all, the numbers for wages and taxes withheld are correct, but I don't see where I can check if the EIN was correct. I know the correct employer name came up when I imported tho.

The EIN should be there.  But if the correct employer name came up I am pretty sure you have nothing to worry about.
Thanks for using TurboTax!

I just downloaded this year's that was transmitted . 7 pages total, not a single form w-2 like I found in my 2017 return which I downloaded to compare. Now I'm really confused.
