I have been using Turbo Tax for 20 years and each year gets a little bit easier. I have complete confidence in their process and filing is easy and worry free.
Two or three times I was asked if I had carry-over from my 2012 Return. This meant that I had to open the TurboTax 2012 Return and make a calculation in order to determine whether I had a carry-over.
Since the information is available to TurboTax (last year's return is stored on the computer), it would be really cool to have TurboTax make this calculation by, itself, referring to the 2012 Return.
