I've added approx $8k of sales tax to my deductions (we bought a new house and lots of furniture) the amount isnt being pulled into my itemized deductions. Why not?

[pkeslter]

This amount would make my total itemized deductions greater than the standard

Furniture is not a "major purchase" for which you can deduct sales tax.

Sales tax is an itemized deduction. “Major purchases” that you can enter for the sales tax deduction include:

Motor Vehicles (cars, trucks, motor homes, RV’s, sport utility vehicles and off-road vehicles

Aircraft or boats

Mobile homes

Manufactured housing

Building materials for major home improvements

You cannot deduct: furniture, jewelry, home electronics such as TV’s or computers

Your deduction is likely being limited to $10,000.  

For tax years 2018 through 2025, the combined total of the state and local taxes section of Schedule A Itemized Deductions is limited to a maximum of $10,000 even if the total amount is higher.  This is true whether you are claiming state and local income tax or sales tax.
