The full Turbotax statement is "Heads up! You have a W-2c coming. You can still file today-this won't affect your return. Since you deferred some of your Social Security taxes last year, you'll get Form W-2c from your employer once you've repaid what you deferred.
When you get this form, make sure it's for deferred taxes only and then keep it with your tax records. There's nothing else you need to do."
