How have you been filing? Did you use the Online web version or the Desktop CD/Download program? You can buy the Desktop program any where you want or directly from Turbo Tax. Look for sales. Costco does have a sale price right now. I just bought mine from Costco. If you buy in the store you get the CD but you can use the download method instead to install it. If you buy from Costco online it is only for the Download install so you have to pick Windows or Mac.
Or you can start an Online web return here,
