How do I enter a W2-C?

My wife and I both received a W-2 from our employer; however, the amounts in line 12 and line 14 were left off.  So, our employer issued us each a W-2c with amount in lines 12 and 14 only.   I do not see an option to enter a W2c in TurboTax.  Please tell me where the program allows me to select a W2c to enter.
