Have used this service for many years. It is very reliable. There is some difficulty retrieving information from some banking facilities but over all works well.
The program walks you through each step in a very easy to follow process until it comes to a number of very annoying and potentially compromising questions about whether you want to share your information with INTUIT (hard to opt out but you can), defaults to save your credit card, bank, and ID information (you can opt out but you have to pay attention or it defaults to yes), and even providing Drivers License numbers that really isn't needed but you don't figure this out until you have already entered it. In this day when the entire planet is worried that the internet is collecting and storing our personal info that could be compromised easily, I would like to see TurboTax become a better partner with their customers and not play this horrible game of data mining.
