I really need to do a t1 adjustment. I don't need to wait until the Notice of assessment as the slip I need to add will be not submitted in the CRA account. I used turbo tax Premier. I received the confirmation code stating that my return has been submitted and received by CRA, however I don't have the option "Re File". I tried the option "Changing your return" but the system tells that it's not possible change the return because has not been submitted!
Please urgently advise how I can do a T1 adjustment. Thank you.
