Same problem on 2019 return. Used TurboTax Premier CD. Would not e-file. After 3 phone calls and no solution, a 4th customer service rep solved the problem. First, he had me uninstall the CD TurboTax app from my Mac Book Pro and then download new TurboTax Premier software for MAC from the TurboTax/Intuit website. The new software immediately downloaded updates. I then
e-filed without a problem. I was not charged for the downloaded Premier software. The customer service rep tried EVERYTHING (2+ hours on phone) before replacing the CD with the downloaded Premier.
Solution: Replace CD app with app downloaded from TurboTax/Intuit website. I hope you don't have to spend hours on the phone before reaching that final step which works.
