Ammonia is not amphoteric. You are probably getting it confused with its conjugate acid, Ammonium, NH4(+).

I thought NH3 was amphoteric because it can act as both a base and an acid depending on what it reacts with
for example in 2Na + 2NH3 = 2NaNH2 + H2, NH3 acts as an acid because it donates a proton
in NH3 + HCl = NH4+Cl-, NH3 is accepting a proton meaning it acts as a base
