If I understand correctly, I heard that you can not do efiling in different TT accounts. All efiling needs to be done in the same TT account that TT was originally activated in. Say if you share TT account with your other family members for efiling, everyone will be able to see each other's filing history and details. That sucks. TT basically just made this change to have everyone buy their own software unless you're ok sharing your efiling info with whom you're sharing the account with and vice versa. This is just what I heard since I have not done it myself to prove this is the case yet.
