You do not want to do what TurboTax calls "transfer." When TurboTax says "transfer" it means transfer information from your 2023 tax return into your 2024 tax return. What you want to do is copy your .tax2024 file from the old computer to the new computer, then "open" it in 2024 TurboTax on the new computer.
TurboTax will not automatically find a .tax2024 file that was copied from another computer. When you start TurboTax on the new computer, on the first screen click "Find a Tax File" to go to where the .tax2024 file is and open it. After you have saved it once in TurboTax on the new computer, then TurboTax will be able to find it automatically.
As VolvoGirl said, if your .tax2024 file contains a state tax return, you will not be able to open it on the new computer until you have installed the state program.
