  We define various types of "phantom" stars that may appear in the TESS Input
Catalog (TIC), and provide examples and lists of currently known cases. We
present a methodology that can be used to check for phantoms around any object
of interest in the TIC, and we present an approach for correcting the
TIC-reported flux contamination factors accordingly. We checked all 2077 TESS
Objects of Interest (TOIs) known as of July 21st 2020 (Sectors 1 to 24) and
sent corrections for 291 stars to MAST where they are integrated into the
publicly available TIC-8, updating it to TIC 8.1. We used the experience gained
to construct an all-sky algorithm searching for "phantoms" which led to 34
million updates integrated into TIC 8.2.
