Get your taxes done using TurboTax

I have been trying to  get in for hours to the deluxe program that I bought.  Had an account and signed in to it and thought  i could down load with license code but would not let me or sent me somewhere else.  Now when I try and download the program it tells me that it has already been downloaded but I have no idea how to get it downloaded so I can use  it.  Please help or tell me how to start again on the basics???? or make like I am loading it for the second time??  Thanks
