I have a problem with auxiliary verbs in questions with interrogatives.
I can't feel the difference between following questions.
"What do tenses use in the essay?" or "What tenses use in the essay"?
Could you help me?

The second one, i.e. "What tenses use in the essay?" is wrong. The first one is correct. It doesn't make sense without the auxiliary verb. Consider this - Who are you? You can't say "Who you?" Here, "are" is required to render the sentence complete. You can modify the second one as "Tell me what tenses use in the essay." Just like, you don't say "Where you live?" You say "Where do you live?" or "Tell me where you live." Also, "Tell me who you are." would make it correct. https://learningenglish.voanews.com/a/forming-questions-part-1-subject-questions/4550920.html
You also can't say "Tell me where do you live." Although, you can use "Tell me, where do you live?", that is, it can be used but necessarily with a comma. Which is correct (if any): "please let me know what do you think"? or "please let me know what you think"?
You need to understand how to frame questions. What exactly are you trying to say with your sentence?
