Hi Beth.
Well, if you validate it with a simple if, something like this:
<?php if ( get_field('fireplace' ) ) : ?>
// do something
<?php the_field('fireplace'); ?>
<?php endif; ?>
This will show the field only if the field “fireplace” have something, this works with text fields and any field as well.
Here the docs about it https://www.advancedcustomfields.com/resources/true-false/
Like a extra point. To print the value of a custom field, you can use directly the function the_field('your_field_name') but if do you want to check or save the value of the field in a variable, you can use get_field('your_field_name')
