If this is not my first time to NETFILE a return using TurboTax, but the first time I am expecting a refund, can I input the direct deposit info on page 4 of the return?

I do not have My Account set up, so I am wondering if I can provide the direct deposit information right on my return before netfiling it, or do I have to call CRA or submit the Direct Deposit form?

After you file

You can set up direct deposit through your tax return in TurboTax, but then you will not be able to use NETFILE. It is better to contact the CRA to set it up, as it will be done quickly and you will be able to file online.

Here is how you can contact the CRA: https://turbotax.community.intuit.ca/replies/2647704
