I am using TurboTax 2019 on my iMac. I completed my taxes in late March, but did not file them due to the deadline extension. When I opened TurboTax today, automatic updates ensued, and my return was missing. None of my work was retained. I searched my computer for files with the extension*.tax2019 and looked in the recycle bin but I could still not find it. How can I restore my work?
