To close the loop on how I resolved with this question -
I was able to find a document from Well Fargo from February which stated the sum of the WF escrow account. When I subtracted out from that escrow total the monthly mortgage portion paid into escrow for the months I'd paid the mortgage up to that point, I backed into a number similar to the "Property Taxes to Wells Fargo NA 3.000 months at $484.88/month" total. No payments were made out of the WF escrow account toward county taxes in 2017. So my presumption then was that the $1450 amount went into escrow and would be used to pay property taxes in 2018 rather than 2017, so I only reported the $1770 number as county taxes paid at closing for 2017.
