Spent hours on the phone with TurboTax and the IRS with no resolution; just mail in the returns...
My solution was to create accounts with the IRS for IP PIN numbers, (Identity Protection PIN). If filing jointly, each taxpayer needs a separate account and IP PIN number. These are entered near where a signature would be. In TurboTax, you have to go to Federal Return and choose the option for Other Tax Options. In its menu will be a link to enter the IP PIN numbers.
After over 10 rejections, my e-file was finally successful. Hope this helps someone!
