When it asks about salary on the resume page, how do I answer it?

I'm sorry, this is a short-answer literature forum. We are unable to assist you with unrelated questions.

I would advise you not to write resumes on your own. It's better to order some professional resume help (here https://resumeget.com/ for example) and get your resume done quickly with all required information. It's cheap and saves your time, so I think It's not the worst option 4 you.
