If you used the Desktop program, you need the data file ending in .tax2023 to transfer. It should be in your Documents then in a Turbo Tax folder. Or search your whole computer for all files ending in .tax or .tax2023.
I think when you first open the program on the Welcome screen should be a Transfer button. Or maybe you have to first click on Begin.
