Are you sure you are looking at the fees for do-it-yourself and not for Live Assisted? The fees for DIY are based on the version of the software you use----are you looking at the fee for Deluxe, or for Premium? And are you comparing the fees for preparing your return BEFORE March 1 ---fees always increase after March 1 even for DIY software.
