  "abstract": "A detailed collider study of Higgs production in the process $e^+e^- \\to ZH$ is presented within the framework of the Two-Higgs-Doublet Model (2HDM), with particular emphasis on mis-aligned scenarios in the Type-I realization. The analysis is performed at a future $e^+e^-$ collider with $\\sqrt{s}=500$~GeV and an integrated luminosity of $10~\\mathrm{ab}^{-1}$, considering heavy Higgs masses in the range $160 \\leq m_H \\leq 400$~GeV. The analysis covers heavy CP-even Higgs states with non-fermionic decay modes such as $H\\to WW$ and $H\\to hh$, and incorporates final states arising from leptonic and invisible $Z$ boson decays. Fast parametrized detector-level simulations are employed to evaluate selection efficiencies, signal--background discrimination, and exclusion sensitivities. It is shown that values of $|c_{β-α}|>0.1$ can be excluded at the $95\\%$ confidence level over almost the entire range $1\\leq\\tanβ\\leq10$ in the $H\\to WW$ scenario, while the $H\\to hh$ channel provides lower sensitivity.",
