I do not know the details of this issue. We are a software company and we are not authorized to answer such questions. I would like to suggest you contact your local IRS office. They can give you the best answer.
According to my experience, you may need to file W-2C and W-3C to correct the w2 errors. You may need to file 941-x and 940 if you have errors on form 941 and 940. Please double check with IRS.
1. If you need to file W-2C and W-3C , you can use ezW2Correction software. The current version ezW2Correction software can print W-2C and W-3C for Year 2005 to 2014.

ezPaycheck software .
3. We do not have software for 941-x. You can check with IRS. I think you can download this form and fill in manually.
Please let us know if you still have any questions.
Thank you.
