No, that box 1 figure will just be the mortgage interest you paid. Your property taxes may not be on the 1098.
The older 1098 forms (pre-2016) used to put property taxes in box 4, which was a blank "write-in" box. But now there's no specific box for property taxes (box 4 is now "refund of overpaid interest"). Unless you see a box with "property taxes" or "real estate taxes" typed in (box 11 "Other" is a possibility), then the taxes probably aren't shown on the 1098.
If you're unsure what you paid, and you pay your taxes rolled into your mortgage payment, then you may need to give your mortgage lender a call. In addition, many counties/municipalities have on their web site a property tax database accessible to the public. If so, you can enter some brief identifying info and verify property taxes you paid, usually going back several years.
