Thanks for your response @EPond22!
Yes, I understand it can take some time but it is the only method to downgrade your TurboTax Online account.
Although you can download the .tax2019 file by clicking Save your 2019 return to your computer, this file cannot be imported into TurboTax Online to continue as a return. In this case you would need to start the return over and re-enter your data.
Let me know if you have any more questions!
