Constant upselling. Every time I log back in or advance to a new section, I am constantly peppered with some other service. Please record my answers the first time and stop bothering me. My taxes are basic, I don't need your premium services!!! Another issue, when I was attempting to complete my returns, an address for one of my financial institutions was incorrect. But I was only allowed to update the zip code. The zip code was correct, the state code that Turbo Tax had was wrong. If you are going to flag an address as incorrect, allow the user to make any and all updates to it.
It's easy and I can do everything by myself. If I have questions or need help, turbotax has a great help system when I need help with anything I am stumped on.
