Thanks to everyone for posting - I'm here because I have the same issue (TT 2023 Biz not finding my QB desktop 2021). Intuit has done everything they can to do away with those of us that use the stand alone software. The only option now is subscription. Other competitors are the same. Glad I'm retiring soon so Intuit won't have any of my business any longer. It simply shouldn't be this hard in my opinion!
I'm going to post it into TT manually since I've wasted way too much time already thanks to Intuit.
