Prorated property tax miscalculated at closing table

[Gretchen Williams]

I sold a 12 unit apartment building in November 2020.  The deal was finalized and all money dispersed.  A month ago the title company let me know that the property tax proration was wrong on the closing documents and I owe over $9000.  I am trying to figure out if I am responsible for this , or is this something that Title Insurance can cover.

thank you!
