The problem still exists as of March 14. I installed and re-installed, turned off anti-virus, uninstalled and reinstalled state, detached and reattached form 8453, no luck e-filing Federal and California State 1041s. Finally, at suggestion of Gemini AI, I e-filed only Federal. This worked. I waited until Federal returns were accepted (overnight even!) and still CA 1041 e-file returns error code 54. It is March 14. Intuit needs to fix this problem!

Same error when I attempted to e-file. Called TT and opened a support request. Planning to follow up to ensure a satisfactory resolution.

Spent an hour to get to level 2 support and they recommended to ensure that .NET Framework 3.5 is checked.

TurboTax desktop requires Microsoft .NET Framework 3.5 (including 2.0 and 3.0) and 4.8 or higher, which can be enabled via Windows Control Panel under "Turn Windows features on or off"
