The TurboTax Desktop software cannot share a tax return data file between two computers, even if they are using the same license code. The only copy of the file is stored on the hard drive of the computer that created it. You could copy the file to the other computer, but then you would have to keep track of which computer has the most recent version, and always copy the most recent version of the file to the other computer.
The name of the tax return data file ends with .tax2025.
