I netfiled my CRA return and my T1135 but I then realized I needed to amend both the CRA and the T1135. So I've today refiled my CRA but I can see no way to refile the T1135. All I'm offered is "Netfile T1135" which give me a message "We're sorry, the Canada Revenue Agency was unable to accept your NETFILE T1135" and "NETFILE submission was already confirmed. Not letting this second submission pass through. Do a REFILE".
Any ideas how I do a refile?
