2106 Federal - Unreimbursed employee expenses using home office, where to claim EXCESS REAL ESTATE TAXES

I have form 2106 unreimbursed employee expenses and use my home as a home office

I own the home and pay mortgage + Taxes

Under:

Personal/ Deductions & Credits/ Property Taxes 

 

Turbotax says: If you paid REAL ESTATE TAXES for your 2106 BUT ARE NOT ITEMIZING - DO NOT ENTER YOUR REAL ESTATE TAXES HERE. ENTER THEM AS EXCESS REAL ESTATE TAXES LATER.

I am not itemizing.

WHERE DO I ENTER THEM AS EXCESS real estate taxes so they carryover? 

 

Form 2106 does not generate a form 8829 (THIS IS NOT a schedule C).

 

So where do excess real estate taxes go?
