I want the basic at 59.99 not the delux at 79.00. Why cant I change it?

I don't know where you are seeing those prices.  
Online Deluxe is 59.99 here,  <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/personal-taxes/online/deluxe.jsp">https://turbotax.intuit.com/personal-t...>

You must be looking at the Desktop CD/Download program for 79.99 here,

Online and Desktop are totally different pricing and programs.  The Desktop program has more features and advantages over online.

If you need to do a 2017 return you can only buy Deluxe or higher.  Basic is not available for prior years.  <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/personal-taxes/past-years-products/">https://turbotax.intuit.com/persona...>
