If you are using TurboTax CD/Download, you can install it on up to 3 computers. Each individual will have their own return file, which can be password protected. So, as long as people are willing to share computers, then each person can prepare a return without being able to open the other person’s file.
If you are using TurboTax Online, no. You will all have to login to the same account, and anyone who can login has access to all the returns and info.
