SET READING LOCATION IN SOURCE - How do I do that?

Hi, my ebook, when opened, starts 5 pages in; skips the cover, title page, TOC, etc.

I wrote Amazon about this as it involved using their viewer. This is how they responded:
===============
Hello from Amazon Kindle Publishing.

Thanks for writing to us.

The content would open at the start reading location / "go to beginning " set in the source.
===============

Anyone know how to do this?

Thanks.
