Turbotax is not a tax preparer and does not practice before the IRS or act on your behalf. You may try calling the taxpayer advocate. https://www.irs.gov/taxpayer-advocate
If the IRS rejected your return, you should have printed a copy of your original return, signed it and mailed it in. This would not have been a 1040-X amended return since you never filed an original at that point. I don't even know how you got Turbotax to print an amended return, unless you changed other details.
