How to add a new tax code?

SOLVED

I am from Ontario. Most of my purchases are HST added. But one insurance item is PST added.

I tried to add a new PST Tax code for my purchases.

I selected Setup-settings-Company-Sales Tax-Tax Code.

In the code, I put PST and tried to select the PST. But in the selection window, only HST shows up.

What am I doing wrong here? How do I add PST with corresponding rate?
