After you file

Thanks for your reply,however,i have a friend who is an accountant helped out,found out i am not supposed to claim employment expenses because i am self employed,btw she helped me to call cra and edit all calims to $0,months later i have got a letter from cra asking for the tax payment,because of no claims i have to pay more tax,and my friend helped me to file a T1 ADJ E to cra in early June which I still don't see any updates on mycra,wondering should I just refile my tax for 2018 again?Does it work like this way?

 

Thank you!
