I made a mistake. I have previously filed W2 to SSA through Quickbooks. Quickbooks showed I would received message when accepet. I have not received any email. So I used TaxBandits to file W2. Then TaxBandits informed me that it's a duplicate submission and let me contact SSA. But SSA is too busy, the calling hold time is too long.
Will duplicate submission affect my employees's income in goverment syestem? Should I file W2-c to SSA?
