I finally got through to TurboTax on the telephone. Mustafa kindly informed me that my Costco purchase will not work online. If Costco will not refund me, then I'm just out that money. So now I've paid twice. My bad for not seeing the fine print on the cover of the desktop version that does state that it "Requires Windows 11 or macOS Sonoma 14 or later." That means I will have paid $300.00 this year to TurboTax for one tax return.
Further, in the past, the desktop versions were good for up to five different refunds. The online version is only good for one. So even if you're a married couple, if you're filing separately you will have to pay for TWO online versions.
I am not pleased at all.
