How can I correct a Form 1099 or W-2 that has already been sent and accepted by the IRS or SSA?
QEF does not support corrected forms at this time. Once the original e-filing is accepted:
To file a corrected W-2, go to the SSA website and file the corrected form, W-2C electronically. You can also use the IRS website for forms and instructions.
To file a corrected 1099, use the IRS website forms and instructions for corrections.
