If I say, "How did she knew about it?" Would it be correct? If you use search engine for "did knew", you get hundred thousand results. Are they incorrect? I'm confused about this grammar structure.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.
No, it is incorrect. The sentence should read "How did she know about it?", although probably the sentence "How did she get to know about it?" would sound more natural.
I think you should look the structure up in a common grammar book.
