If the only changes to the forms W-2c & W-3c are to the local data for one employee reported on Line 14 Other, instructions on the IRS website state Not to send either Copy A for Form W-2c or Form W-3c to the SSA.  Is this correct?  And if I do need to send to the SSA, do I need to use the RED preprinted forms and mail the copies?  I use the Quickbooks Desktop Payroll version.
