We investigate the two-proton ($2p$) emission from $^{16}$Ne with the time-dependent $^{14}$O$+p+p$ three-body calculations. Two $0^+$ resonances are suggested to participate. For the $0^+_1$ resonance, the true emission of the spatially localized two protons is dominant, if the single-particle $s_{1/2}$ resonance locates above the $2p$ energy. By evaluating a time-evolution probability, the $0^+_2$ resonance is suggested at $\cong 3$ MeV from the $2p$ threshold. The inclusion of $0^+_2$ resonance makes the true-$2p$~emission more dominant in the time-dependent calculations.
