TurboTax runs on Windows 11 (and Windows 10).
Some people (probably those that have not had a version of TurboTax for years prior to 2023 installed on the particular PC) have had problems with TurboTax complaining about missing DLLs on their Windows 11 PC and have had to manually install Microsoft's x86 Visual C++ Redistributable package to correct that:

Otherwise, why to you believe that TurboTax doesn't run on Windows 11? Saying what something doesn't do isn't diagnostically useful information. What does happen when you try?
AND...the use of "cpa" in your screenname, and talking about "a network guy"
....adds in the following questions.
1) Working on your home computer? or a computer at work?
2) Is it the Consumer software you are using (Online Free, Deluxe, Premium, / Desktop Basic, Deluxe Premier...etc..etc)?
3) OR is it the Professional software (Lacete...ProSeries...ProConnect)?
This forum only deals with the consumer software.
Professional software users probably have their own Forums on their websites.
TurboTax is not licensed for use by paid preparers.
