After you file

When you send the photocopies, or the copy for Fed, of your W-2(s), that should resolve the issue with the IRS.

To understand your actual refund, or tax due, 

you would  have to revise your TurboTax return to match the W-2 withholding you will be supplying to the IRS.

Make a copy of your originally filed return first, for your records.
