Hello @wawadudu789-gmai, thanks for your post.
If you have a simple tax return, TurboTax Online in Canada is free to users.
Here are the common scenarios which are possible to do with TurboTax for free:

However, if you have additional scenarios, or need to fill out additional forms for your return, you may need to pay in order to file via TurboTax.
