Why does TurboTax list my property taxes as provided on a 1098 when it wasn't?

Odd. TurboTax shows my property taxes as linked to the 1098 from my mortgage company (with that company's name listed)... but I pay my own taxes and nowhere on the 1098 is there an entry for property taxes paid. Why does my mortgage company show as having paid and shown on a 1098? Is this a bug?
Elsewhere I did enter my mortgage-holder with a 1098... but nothing about property taxes.
