I did mine and my husbands return, but now I need to do another family member which I've always been able to do in the past. With this new software, I can't see how to do/where to go to do a new filing.
Are you using TurboTax Online? If so, the FAQ below will explain how to create additional accounts. Each user account can only submit one return but you can create up to 5 user accounts under one email address.
