How can I find my old account

Hi, I am trying to locate my account that I created to do taxes last year. I know I did them through TurboTax because I have a confirmation email from last year detailing how to track my refund and that I can save a pdf version on my account page. However, when I use the methods suggested to locate my old account, the only account that appears is the new one I made this year to file my taxes. I accidentally made a new account thinking I was resetting the password for the old one, the email address and phone number are the same as they were for last years account. Please, any help at all would be appreciated I need last years tax return to finish filing this year. (Last year was my first year filing).
