Also having this issue and the IRS males it very clear not to mail in an Ammended tax return if it was originally efiled. TurboTax needs to fix this right now. If by mail they need much more information such as XML documents stating what changed, etc. Help Please, so easy just to allow e-file, I redid everything and can push trhe efile button, but get the same duplicate SSN issue. Since its ammeded, it should have a duplicate SSN
