If you filled with TurboTax then your tax returns would be available in your tax timeline. You should see all prior years that you filed threw TurboTax (may require PLUS purchase to view/download/print returns). If you do not see prior year returns in that section then you may be logged into the incorrect account. One email address can have multiple user ID's associated with it. To try to access the old account try the following:
