Is it a *.tax2024 data file? If so, where did you get it? Was it prepared in Online TurboTax last year, and you downloaded the *.tax2024 data file? If you paid for 2024 Online TurboTax last filing season, TurboTax Support "might" furnish you the 2024 desktop software if you need to open it.
TurboTax Support, currently Mon-Fri 5AM-5PM Pacific.
