How can I tell word that a page is the cover page in a booklet.

I have a booklet that is 5 pages front and back. The cover page is not
being recognized as such and it is not being put on the correct (right side)
of the printed sheet.

Thanks

A booklet needs to be a multiple of 4 pages. If your booklet has 5, you need
to insert blank pages in the appropriate places. There is no concept of a
"cover page" - that's the first page of your booklet. You need to insert
blank pages wherever you want your covers to be blank (eg. inside front,
inside back, outside back).
