I am attempting to EFILE multiple client T1 returns and receiving the same error. I haven't changed anything since last year, except for updating my EFILE password. The error appears to be specific to EFILE Identification Fields: It reads as follows:
Transmission contains invalid or missing data: EFILE Identification Field(s) Notice of Assessment Retrieval Indicator, First time Filer Indicator, T183 Electronic Signature Indicator, T183 Electronic Signature Date, T183 Electronic Signature Time, RC81 Electronic Signature Indicator, RC81 Electronic Signature Date, RC81 Electronic Signature Time.
Screenshot attached.
