@Mike306 If you have the Desktop CD/Download installed program you don't use Accounts. You just start a new return by going up to the top black menu bar first item File - New Tax Return.
If you are using the Online browser version, Online is only good for one return per account. But you can use the same email address for 5 accounts.
