Solved
This year was the first year I used Turbo Tax for my tax returns ... purchased/created an account. I need to now file another tax return for my son ... can I use this same account? How do I start a new tax return?
Unfortunately, no. When using the online versions, you will have to start a new account with a new unique user ID for another tax return. The online editions are only good for completing one tax return per account and user ID.
