Past years Turbo Tax software stored on my computer

[barmat]

I have rental property that I depreciate every year on my federal tax return.  I have been doing this for many years.  I keep the Turbo Tax software from past years on my computer, thinking that when I do my current tax return, it looks back to prior year software to transfer data for that rental property into my current tax return.  Do I need to keep all those past years of Turbo Tax software on my computer?

Also, I have a Windows 10 computer.  I understand that Turbo Tax software for tax year 2025 will not work on a Windows 10 computer.  If I buy a new computer with Windows 11, can I install those past years Turbo Tax software, which has my tax files in it, on the new computer so that when I do the 2025 tax return it will calculate the correct depreciation for my rental property?

No, not really. You want to retain the .taxXXXX files and the (FULL) PDFs for your records, however.
