I don't want to use the "LIVE" function, I just want to purchase a DVD or do a download.

Buy the personal Desktop CD/Download programs here or look in stores for sales.  Costco has a coupon right now.

Ok ... then if you have not paid for the Online LIVE version you can simply abandon the online account and use the downloaded/CD version instead.  

 If you use the DOWNLOADED/CD version then you can use  ANY version ... if you don't need to file a state return choose Basic and  if you do need a state then Deluxe.   https://turbotax.intuit.com/personal-taxes/cd-download/

You can also purchase the CD/download from various retailers such as Costco, Amazon, Walmart, Best Buy, Staples, Sam’s Club, etc. etc. etc.
