A square wave IS the base frequency plus ALL[1] the odd harmonics (https://en.wikipedia.org/wiki/Square_wave#Fourier_analysis https://en.wikipedia.org/wiki/Square_wave#Fourier_analysis explains it better than I could).
[1]: Yes, so in reality you neither get an infinite set of harmonics, nor a perfect square wave.
