Its likely a syncing issue because the funds are on that address as you can see here : Address addr1qy55jn473as7ne9005yjz6tfkxdzd828atmd7pd2h84uxf370ju0gqj394agp2m23lqqz4rj4h25zzfeggnj928902jqchp7mt - Cardanoscan
So try to resync the wallet (im not familiar with Trust wallet to be fair) or restore the wallet in a other software wallet like Typhon (not 100% sure if compatible).
