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!
