After you file

It is not clear just what the W-2C changed. If it does not change the amount of tax owed or refund then amending is not necessary.

Each tax year is separate and must be amended separately. Amended returns can only be mailed. NEVER mail more that one amended return in the same envelop of the IRS mail room will just attach them together and one will never get processed.

Amended returns can only be mailed. It is suggested that it be mailed certified with return receipt (or other tracking service) to verify that the IRS receives it.

See this TurboTax FAQ for detailed amend instructions:

You can check the status of the amended return here, but allow 3 weeks after mailing.
