FIXED !
I had this problem this morning and went around in circles trying to solve the issue.
After reading some other posts about external disks, I removed a 32GB USB blank but formatted memory stick in my machine and it worked...TurboTax fires up correctly. Put the stick back in and it requests me to enter an activation code.
I have tried it 10 or 12 times and removing the stick makes it work and putting the stick back in causes the activation code request.
This stick was not in there when I installed Turbotax way back last December.
Does anyone have an idea what is happening here
