Extra line break after checkboxes

On a page where I’m using a form, there is an extra line break being injected after each checkbox. It is not coming from the form plugin- Gravity Forms insists it must be coming from the theme. Any idea how I can fix this? The code actually shows an extra
<br> after the input and before the label.
