After you file

Do you use Turbo Tax Online version or the Desktop program?

If you used Turbo Tax last year you should start a brand new account for yourself and not transfer from last year.  You can not remove a spouse or switch the order of names.

 

Online is only good for 1 return.  But you can use the same email address for 5 accounts.   How to start another return in the Online version
