My ex spouse and me are separated and I would like to transfer her 2019 return to her own profile (separate from mine) so we can complete on own (no access to each other)

If you are using TurboTax Online, unfortunately, a return cannot be transferred into a different account than the one it was created in. The only copy to be shared would be a paper copy.

 

Because with TurboTax CD/Download, you are not using and OnLine account, you have your own file. If you wish you can import a copy of your own personal profile, 2019 TurboTax.tt19, from your computer to another computer and transfer from there into next year's return. 

 

Thank you for using TurboTax.
