How do I know if i have filed tax return? it seems that I have filed but I haven't received any notification or confirmation. thanks

Hello @urba424555 ,

If you used TurboTax Online to file your returns, you'll see its status on the Tax Home screen of your account. You should also be receiving emails letting you know when your e-file status changes.

CRA website will also show you the status of your tax return. 

Hope this helps.

Thank you.
