Let's say you need to only charge your client's your Entertainment Tax on an inventory item.

Here's how you can change the tax applied to an inventory item:

First, click the three dots next to the item
Then, click 'Edit'
Next, remove unneeded tax or add any additional tax types
Finally, click save

Your item will now reflect the tax you applied on this project. Please note, this will not reflect on any other projects. If you'd like to change the tax types whenever you add this item to a project, you'll want to edit the item.
