Get your taxes done using TurboTax
if you can't upgrade to Win 11 at this time, and don't like or want to use the online version which I agree is a different experience to desktop and has limitations (no forms mode, only 1 return per account), then you will need to seek out other tax s/w that still supports Win 10 this year - HR Block or TaxAct.
If cost is the issue rather than functionality, there is an offer intended for Win10 users to switch a desktop license to Online Premium Fed+State for no extra cost; but note this is only good for 1 return. See offer details and comments in the screenshot below when trying to install desktop on Win 10.
Another more technical approach others have used is setting up a Win 11 Virtual Machine (VM) on their Win 10 machine to run Turbotax desktop within the VM.
