How do I cancel bundle plus as I do not need this device?

If you mistakenly added the Plus Bundle to the Free version of TurboTax, you cannot just remove this from the billing screen. Your only option is to start another Free return and be sure you do not accept any upgrades or promotional offers such as the Plus Bundle.

This situation of not being able to remove the Plus Bundle is a scam, you should be ashamed of yourself.

This is not right. 

I did the taxes on the free version and for some reason at the end I am hit with $23.98 + tax for plus bundles. I cannot remove them but if I were in the USA I could. Why can't Canada do that as well instead of having to start all over again.

That is utterly ridiculous. I finish everything on the free version and accidentally hit the bundle button and have to start again.
