CRA's NETFILE is currently closed for annual maintenance, so unless you printed your return to mail it to the CRA, you haven't filed yet.

If you've already paid for your return (which it sounds like you have), all you need to do is sign back into your account on or after February 26th (when NETFILE opens) and pick up where you left off. TurboTax will guide you on what to do; you'll just need to follow the steps.
