The term you're looking for is hanging indent. Look that up and if you still have questions let us know.
You can accomplish a hanging indent by these two methods:
Open tab panel, place cursor within text, drag the two triangles to the right where text will align. Drag the top triangle back to the left where first indent only will align (this is the hanging indent). Add a tab to the location where copy after underscore aligns. Enter a tab after underscore
Open Paragraph panel, place cursor within text, enter numeric values for each: left indent and first line (this will be a negative value)
Thank you very much for taking the time to explain this in detail. It was exactly what I needed to do this.
