Hi, I am also in Shenzhen and need to get to Chengdu. I can't find any bus schedules or ticket prices on the Internet for Yinhu or Longgang Long-distance Bus Stations.

It is about 2,060km between the two cities, so there is just one or two long-distance bus running for this journey every day. As I know, no bus runs for the journey departing from Yinhu or Longgang Long-distace Bus Station. I know two buses leaving from Fuyong Bus Station at 11:30 to your destination. The bus station is about 4km from the airport.
