This doesn't seem to make sense.
The instructions in the first paragraph of the first box say:
If you paid real estate taxes but are not itemizing deductions, do not enter your real estate taxes here. Enter them as excess real estate taxes later.
Then the third paragraph says:
If you paid real estate (property) taxes on the entire home, enter this amount here, and later go to the deductions and credits area, and review the property tax information.
The next box says:
If you paid real estate taxes but are not itemizing deductions, enter the taxes you paid here.
