I am an American Citizen who owned a property in Ottawa, that rental income is the only income I have in Canada. Does turbotax work for my case? what's my best option?

Yes, you can prepare your return using TurboTax. If you already have a TurboTax account in the US, you can use that same login for TurboTax Online Canada or the TurboTax Canada App. If you just want access to the forms, without having to go through the full EasyStep interview, you can use TurboTax Basic CD/Download (for Windows).
