Filing taiwan taxes while overseas?

Has anyone tried to file taiwan taxes while overseas? Due to the virus situation I probably won’t be going back to taiwan until next year. I originally left taiwan back in Jan and was planning to return in feb, but now I’m not so sure. Can I just file when I return? All my income is foreign income / overseas investments but I stayed over 180 days year so I assume they’d want to tax my worldwide income? I already filed taxes in the US and there is no tax treaty with Taiwan.

I checked but none of the links seem to lead to an application

That’s for paying tax owed. Filing is through , download it and then pull all your hair out in advance.
