If you used the same account then the second return done overwrote the first return. So you should not use the same account.
Online is only good for 1 return. But you can use the same email address for 5 accounts. How to start another return in the Online version

But if you have more than 1 return to do it may be cheaper to buy the Desktop program which can do unlimited returns and has more features and advantages over the online version.

Oh, hopefully you have another account. That's common to end up with multiple accounts. First LOG OUT of whatever TurboTax account you're logged into right now. Then use this TurboTax account recovery website to get a list of user ID's for an email address. Run the tool against any email addresses you may have used
