You'll need to "register" for your CRA My Account. Follow the link below, scroll down to "Option 2" and click "Register".
I am registered. The issue seems to be that when I want to proceed to pay through my bank to CRA, it wants an account number. I cannot find any account number anywhere on CRA site under my profile?
Why does it say CRA cannot accept the file I transferred?!
Please contact CRA for assistance with this matter as they'll be able to assist you further.
TurboTax doesn't have access to your private CRA account information.
Please contact CRA to retrieve your account: 1-800-959-8281
