need to create a template with 4 equally sized textboxes

OR… possibly just 3 equally spaced horizontal lines. ( on a 8 1/2" x 11" page, these lines would be at 2.75", 5.5", and 8.25"
The most important issue, which I cannot seem to solve, is that I need to be able to type freely in each “space” WITHOUT the separating lines moving, save and then open a new document to do it again.
It was suggested by a Microsoft forum to try Libro as, much to my surprise, Microsoft Word was not capable of doing this.

Possibly just use a table with 4 rows / 1 column, and set row height to fixed value.
