I got errors trying to install TurboTax on one PC, had to do my taxes on another PC where I couldn't import my Quickbooks data (QB has to be installed on the same PC). I had to manually enter everything. It would be nice if I could have used an accountant's copy of the QB file on any PC. Entering deductions wasn't very flexible, had to fit them into Turbotax's categories. Help files weren't very helpful, I spent quite a bit of time searching for answers online.
Have to use this to prepare and file but the integration but the federal and state returns is really awful. I had to go to form view and manually edit the state return to get all the information entered correctly. Good thing I am a CPA and have some experience preparing taxes, though not my main focus
Having used Turbo Tax Business for many years, I am impressed with the step by step process of entering my data from my year end spreadsheet. I highly recommend.
Turbo Tax worked well and quickly. Only issue I had was that I was not able to register the product. I am in Canada and the company registered address is in Canada (a US LLC). The tax system was fine with the Canadian address but the registration page would not allow a Canadian province and postal code that i could find. Also could not find a way to contact support regarding the issue.
