Get your taxes done using TurboTax

Confirming the above issue + resolution from BARLECH:- That is, IMMEDIATELY after installing turbotax-desktop, it fails to TRANSFER INFORMATION from prior year's return.

Step 1: Download and Install TurboTax

Step 2. Reboot.  Yes -- even for macOS Tahoe 26.2 -- you MUST reboot.

Step 3: After reboot, re-open Turbotax, and .. drumroll .. the issue is now gone!

It's frustrating that Intuit failed to have TurboTax show a popup asking to reboot - BEFORE further using the desktop-turbotax. Or .. .. this is all by design, to frustrate desktop-app users, to push everyone onto their "online" product.
