I used to use H&R Block, but TurboTax is much more user friendly and is more helpful for expats who file while overseas. Even access to the platform with an international country code was an issue with H&R. My tax situation is pretty complicated, but I am able to navigate the process with the guidance of TurboTax.
Product is quick and easy - but I don't like that they force you into the Premium $44 services. I don't remember seeing an explicit option to accept/deny that service.
