So I'm now seeing that as per error 248 we did have an employee in 2018 and 2019 where Federal Withholding was taken out twice on his paycheck. At this point it's too late to go back and correct the errors. . . W-2s have already been filed, as have the employees tax returns - how do I fix this error now? Also not sure why this issue never came up earlier since I've run the rebuild/verify numerous times since then. . .
