Go to this website to purchase a download of the 2016 desktop editions - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2016 tax return can only be printed and mailed, it cannot be e-filed.

Also note - TurboTax for 2016 does not support Windows XP.  
See this TurboTax support FAQ for the Windows system minimum requirements - <a rel="nofollow" target="_blank" href="https://ttlc.intuit.com/questions/1901571-minimum-system-requirements-for-turbotax-windows-software"...>
