Please explain that some more. So you have started a 2025 return, but the program can no longer find the 2025 data file to continue working on it? What are you using to prepare your 2025 return--Online TurboTax or desktop software? If desktop software, is it for Windows or Mac? If using desktop software, the default location for the *.tax2025 data file is in the Documents\Turbotax folder unless you chose an alternate location. We can tell you more once we understand your situation.
