I can't ammend a 2019 CD/DVD return after it was accepted

1. I have e-filed my fed and state returns  using the CD/DVD version of TurboTax. 
2. I saved and exited.
3. I realized I made a mistake and changed a deduction amount
4. I saved and exited.
5. MY returns were subsequently accepted
6. I checked in TurboTax and it sees both accepted
7. I then tried to eFile again and it says "You have no returns eligible for e-filing"

How can I e-File my amended 2019 return?
