What if my w2c is blank

[stockman]

got a w2c and it is blank all feilds for "previosly reported" and "correct  information" are blank except #13is checked "third party sick pay"

In fact, your corrected form W2C was not blank. It did correct the fact that box 13 - Third party sick pay should checked.

In TurboTax, revisit your form W-2 already entered and check box 13 - Third party sick pay and also check the box to indicate that the form W-2 is a corrected form.
