Sorry Online is only good for 1 return per account. But you can use the same email address for 5 accounts. How to start another return in the Online version
The Desktop CD/Download program can do unlimited returns.
Thats why if you need to do more than 1 return we recommend you buy the Desktop CD/Download program. It can do unlimited returns and efile 5 for free. And you can buy a lower version. All the Desktop programs have the same forms. You just get more help and guidance in the higher versions. Buy the Desktop program in stores or directly from Turbo Tax here
Yikes, did you already do his return in your account? Had you already done your return? If you used the same account for a second return then it overwrote the first return. So if you did his return after yours then your return is GONE.
