In the Tax by Zip configuration if you have the 'Apply tax to selected countries' checkbox checked make sure you actually have United States selected to be taxed. If it says 'No Countries Selected', then it won't work.
Besides enabling the 'Use?' checkbox for a state you want to tax, make sure you have also put a rate in the 'Tax Rate' box. And vice versa.
When testing make sure you are using Taxable products. The tax settings should have no effect if all products in the cart have the Taxable checkbox unchecked.
Also when testing, use the Empty Cart function and add items to the cart anew AFTER making any changes to make sure there aren't elements of the old settings in that cart file.
