Do I need to send additional forms other than the 1090X with my amended tax return after I corrected my property taxes figure?

No.  The amendment will show the net changes only and property tax documents do not get sent.  Print sign and mail it.  If the amendment resulted in a balance due, remit the difference.  If it resulted in an additional refund, you will receive that once the 1040X is processed.
