How To Get Sales Tax Into QB using Syncho?

Since the start, I have been fine with Synchronization, but still unable to
get the Tax in on in-state orders with sales tax (these are reflected back
to the customer in Miva), and in Synchro, we have the Tax, and Non items at
the bottom of the config screen. What do I need to do to get Tax to come
into the right place thru Synchro to QB?

thanks,
