I sympathize, as I am in the same boat--a nice compact form PC with solid state drive, loads of memory, but operating on Windows 10. As it was purchased in 2020, it likely has the TPM 2.0 CPU.
I do find the logic of Intuit's recent message to customers definitively stating that a downloadable version of TurboTax will not be sold for use with Windows 10 operating systems, due to MS' failure to support Windows 10 with security updates. In point of fact, MS has agreed to support Windows 10 users with security fixes on payment of a $30 fee post-October 15, 2025 for another year. I suspect that further extensions will continue for a while.
One would speculate that the real reason for Intuit's decision is that the company does not wish to expend the money to tweak the software to recognize "security updated" Windows 10 software during the download process. That is, is this a PC/laptop using Windows 10 subject to the MS ESA (with security updates) or not? Given how many software changes must be made in the code every single year, due to the copious number of tax law revisions in the federal and state governments, I do perceive the inability of the Intuit coders to develop a software tweak to identify a Windows 10 ESA operating system vs. a Windows 10 w/o security fixes to be specious and unconvincing.
In any case, for my part, after using Intuit's downloadable software (TT Premier) for six consecutive years, I will move to the H & R Block equivalent in 2025. My tax situation implicates investment in gas & oil MLP's, foreign stock equity dividends, etc., which require access to the "forms" review function to correct errors created by the "questions" approach to completion of the forms. TT Online does not offer "forms" review and modification function, so departing from TurboTax next year is a no-brainer for me; I am not paying a couple grand for a new machine, just to be able to use TurboTax.
