I am able to print an invoice but am not able to edit individual items within the invoice including sales tax to be calculated.

Go into your [Customer Invoice] account (or whatever you named it) select the invoice to edit and either 1. double click on the word FORM in the category field or 2. click on the Display Form icon at the right side of the highlighted invoice.  From there you will have access to edit items in the original invoicing form.
