Deductions & credits

in TT2021 the next page after answering yes to "paying real estate taxes, but are not itemizing deductions" is 2 choices and both apply.  I'm confused on which one to check. I have a home office and entered the entire amount of property tax when asked. Should I put 0 for the "Entire Home Excess Real Estate Taxes" and also put the entire amount again in the next area for "Home Office Only Excess Real Estate Taxes"?
