I did my sons 2019 taxes in my account. I want him to establish his own account for 2020. How do I transfer his 2019 data into his new account?

Sorry you can't move or merge accounts.  He will have to start fresh with transferring.  Whose info is in your account now?  Whichever return you did second (yours or his) overwrote the first return.  So if his return is still in your account then keep that for him and make a new account for yourself.  

The Online version is only good for 1 return and account. But you can use the same email address for 5 accounts. To do another return you have to set up a new account and new user name and pay any fees again. That's why it's better to use the Desktop CD/Download program. The Desktop program can do more than 1 return and efile 5 for free.

Sorry--you can't.  TurboTax accounts cannot be merged.  And....if you used your own account and user ID for his return after you prepared your own--you overwrote your return and it is lost.

When you use Online TurboTax, you get one return per fee.  Each return needs its own account and user ID.   If you use the same account and user ID for a second return, you overwrite the first one and lose it forever.
