I need to see what was submitted to CRA after I completed my 2019 return, ie was I due a return or did I owe.

If you used TurboTax Online- please log into your Online Account- and click on your return to open it then on the left-hand side click on- File- continue and it will advise how much you owed or if you will be receiving a refund. If you owed when you filed your return it would have told you and asked how you were going to pay for it. 

If you filed your return and can't find it click here- https://turbotax.community.intuit.ca/community/navigating-turbotax/help/where-do-i-find-a-copy-of-my...
