Can my wife get her own logon to this account?

In TurboTax Online, you can prepare and e-file one federal and up to five associated state returns under the same account login (your account is your username, not your e-mail address). And you can file up to five federal returns under the same email.

You should create a new account with its own unique User ID and password.

No.  There is only one login username and password for an account.  If you are filing a Joint return you have to share the login info.
