This problem is not solved! Tax Year 2022. I repeatedly am receiving the 54 error messages for 1040NR extensions. Steps tried to no avail: 1. Open return and press F9; save return. 2. Update software. 3. Refresh update. 4. Uninstall and re-install 1040NR Program. (Windows 11. Professional Pro Series.) This has cost me half a day so far with no end in sight!
