Both my daughter and I had to file on paper as there were multiple problems when we tried to use electronic filing. The instructions were very difficult to follow in order to correct the problems.
The software would not let me fill in my IRA conversion to a Roth account without an override. This prevented me from E-filing the return, so I had to print it and mail it adding more money and frustration to the tax season.
Ok, so I procrastinated until the very last day to file, thank goodness I had this software, because I ended up stuck at home with no car! It was soooo easy to use and didn't take long at all. Asked all the right questions and had good explanations as well. The audit check is also awesome.
