This is now 2025, I am getting the same error. This is the first occurrence for me, I have used Turbotax for a number of years, I was able to file one return, when attempting the second return, this message appeared, I have followed all instructions; log in as admin, disable my antivirus and VPN...etc...etc.
I have been getting the run around for 24 hours, I was even sent to a troubleshooting number in the US.
Last info received was that the error code TT805 pertains to windows, not Turbotax...
