Previously, I did my mother's taxes for her in Turbotax and my own taxes in CreditKarma. Now I can only access Turbotax documents, not the CreditKarma ones

I used the same e-mail address for both, but now that Credit Karma is a part of Intuit, it can only find my previous years returns for my mother, none for me. How can I get these documents (lost the hard drive, not stored anywhere else)?
