Not quite sure I understand the question, but I think you'll want to open "bullets and numbering" from the flyout menu in the paragraph window.
Select all the text you need and look at the "first line indent" section of Position. You'll want that to be zero. If you want to move the position of all the line beginnings relative to the bulletts, change the tab position.
