I talked with support and discovered the reason TurboTax wasn't finding the existing returns automatically upon startup. I had recently moved a folder, which contained a TurboTax folder which contained my TurboTax files, from the Desktop into another folder on the Desktop and therefore apparently TurboTax wasn't finding the files automatically upon start up. The solution I performed was to move those files into a TurboTax folder in the Documents folder and then open each file and save, so it will find them automatically when starting TurboTax.
