Bus help, anyone?

Thursday will be my first time taking the bus in the city, and as someone with zero knowledge of the buses here, can y’all look at this for me?

I did the trip planner on the GRTC website, and it generated this.

This looks like I just take a single bus (the number 20?) and there are no changeovers anywhere? And the cost is $0.45?

(Thank you for your non-judgement of my navigational skills!😆)
