I can only find tutorials online for making rounded edges on a rectangle, and that works fine with corners in the property.
I need to make a straight line with rounded edges on both ends and for that, the properties>corners>rounded does not work. I've tried 50px or 2px for a line that is 2px wide and literally nothing works, they stay sharp as a razor blade.
Thank you so much! I swear I'm not an idiot. I haven't been using InDesign long, and I just didn't know a line was called a Stroke. to be fair, I must have looked at the Windows list of panels a hundred times and I never even noticed Stroke. Thank you so much, friend!
