The online version is cheaper or free! But it's a bait for your personal, financial, tax information, and asks you to sign forms to give Turbo Tax or Intuit permission to share all your information with it and it's affiliates, partners etc.
The online version is not as "mature" as the CD or downloaded computer version.
So far as I tried, the online version doesn't give you the flexibility of saving your tax return files into different versions, like 2020-Filing-Jointly or 2020-Filing-Separately, to see if which is the best choice for you.
This is the 2nd year I tried the online version, and very disappointed so far!
It takes time for Turbotax to do debugs and optimize it, I guess!
Best regards!
