While climbing through approximately FL190-FL200; the right engine fire light illuminated. I called for the INFLIGHT ENGINE FIRE QRC (Quick Reference Checklist) and my First Officer performed that while I took the radios. The light extinguished within three seconds of bringing the thrust lever to idle. We notified ATC; leveled off at FL220 then immediately started a descent and a diversion into ZZZ. I'm not sure if I missed him reading it or if he missed reading that line; but we did not catch that we should have then conducted the ENGINE INOP APPROACH and ENGINE INOP LANDING QRC's. Knowing that we still needed to run more checklists; but with several things running through my head at that point we forgot that we should have remained in the QRC; we conducted the ENGINE FIRE and the SINGLE-ENGINE Approach and Landing Abnormal/Emergency Cessna Checklists. After landing we stopped on the runway to allow the ARFF (Aircraft Rescue and Fire Fighting) trucks to evaluate. They said no fire; so we taxied to the FBO and shutdown normally. Maintenance was at the aircraft shortly thereafter and removed the engine cowling's for inspection. They had an opportunity to inspect the aircraft before we left the FBO property and they stated that there was evidence the light was probably the result of a bleed leak from a bad coupling. I reviewed the single engine procedures and the emergency checklists after securing the aircraft. I will continue to study these on a more frequent basis to ensure I am extremely familiar with the QRC. In addition; with any future emergencies; I will be sure to slow down my non-flying pilot if they are 'breezing' through the QRC and make them read it in a very slow and deliberate manner. I think I let the threat of fire (despite the light being extinguished) push me towards the approach and landing instead of ensuring we were precisely following correct procedures. I do understand that there is a balance between perceived urgency of the situation and being too 'wrapped up' in correct procedures. My last suggestion is to make a change to the QRC that would help to highlight or draw the eye to any lines that direct us to another QRC. Perhaps a larger font; different font; bold font or another color font.
