Deductions & credits

According to this turbo tax community link. (I'll attach at end)  It says line 23, Taxes and Licensing.  

I personally think they should have a completely separate line item on the Schedule C to make it easy. 
Now I need to amend my taxes for the last two years.  I never added the sales tax as a deduction.
