ESU is critical/important security fixes only - many regard that as sufficient "support" which is fine but technical "Windows 10 support has ended" - see https://www.microsoft.com/en-us/windows/extended-security-updates
At this point tho the technical details are a bit moot as it's clear Intuit's decision wasn't entirely for technical reasons, they waffled about security but also indicated they didn't project enough users left on Win 10; and whether their projections are right or wrong doesn't matter much either, as desktop is only 1% of their revenue and in decline, and they are clearly strategically pushing towards online with 3 different offers now for discounts for desktop/ItsDeductible users to try online, the most recent offer email apparently entitled "The future of tax filing is Online"

The combination of ending support for Win 10, ItsDeductible, MAC OS 13, Basic edition, plus the gammit of online offers will probably put a significant dent in desktop user base from 4mil to closer to 3mil I would guess, we'll see next year how it all shakes out (this is compared to 35-40mil online/live "units" with 20x revenue).
The H/W issue won't go away in 10 months (unless MS extends ESU) - but there are workarounds to allow Win 11 to install on "incompatible" but otherwise viable H/W. The other option is a Win 11 VM and run Turbotax there. Not sure the technical details of these options but they are presumably widely documented elsewhere.
Otherwise if online is not an option (agree) then it's off to HRB or TaxAct.
Good luck.
