You're right! I realized later that the family had already called CRA and notified them about the death. All CPP and OAS payments were stopped and that could be the reason why I could not netfile. I appreciate all the responses!

Hello Geo123, When the year of death is entered for memo purposes (i.e. 2023), the system refuses to Netfile, and indicates it must be mailed. Would you suggest to omit the "date of death" this year and Netfile it? Then do a final deceased return for 2024? Thanks in advance!
