Quick Employer Forms does not support corrected forms at this time. Since you stated it was already accepted by the Social Security administration (SSA), you should file the corrected form, W-2C, electronically if the employee's W-2 was incorrect. You will also have to file a W-3C to correct the totals from all of the W-2's issued.
For additional information, please see the Social Security Administration's Helpful Hints to Form W-2c/W-3c
