No, you don't need a CRA account to get your tax refund.

What do I need? Yesterday, I did the direct deposit with my bank. If I only need that and nothing else, how long do I have to wait?

The CRA's goal is to send you a notice of assessment, as well as any refund, within:

• two weeks, when you file online
• eight weeks, when you file a paper return

I finish all with TurboTax and send it to CRA the February 20, I don't have any answer. Yesterday, I did my direct deposit with my bank. Maybe it's because I did that yesterday, right?

Yes, if you only set up direct deposit yesterday, then they may have mailed out a cheque for your refund.
