Turbotax does not submit your taxes to CRA automatically for you, nor does any tax software.

The software (either free or paid) simply makes it easy for you to fill out the tax return correctly , and including the necessary arithmetic.

You have to decide (a) how to submit your return , ie by mail in or NetFile, and (b ) when to submit your return, assuming you wish to..

Evidently you did not complete the filing process. Go back into your returns and advance through to filing, decide mail in or NetFile and proceed.
