How can I remove padding from a heading 4?

Hope someone can help! I’d like to remove the padding under heading 4 so that the next line is right below (like single space).

It’s still a work in process. For some I changed them to just be bold but I’d prefer them to be “heading 4” I understand I’ll end up removing the padding/lines from all the headings by making this change which I’m okay with. But I haven’t figured out how to do so.
