What does error T804 mean when trying to e-file a T1013 for 2018?
Error message says
"T804: The software used to prepare this file was not certified. Please contact your software developer to obtain the certified version of the software."
I have the most up-to-date version of the software and have my license key entered for TY18. Why am I getting the error message above when tying to file the T1013?
