Then I don't understand the problem. If they don't want anyone else to see their returns then they should setup their own account (which they have to do anyway) with different email addresses. But whoever does the return will have the log in information.
What about 5 accounts? The online version is only good for 1 return per account. You have to pay for each account and return unless someone can use the Free Edition. Oh, are you asking about the Desktop program that you install on your computer? Desktop can do unlimited returns and efile 5 federal for free. State is $25 to efile or you can print and mail state for free. You can sign into another account under File-Sign in
