On the list of profiles, tap on the profile you are interested in. The profile entry should expand to show the profile trigger on the left, and the first few actions of the enter task on the right. Click on the right column, and the entire "enter" task will be displayed. On that screen, in the lower left corner is a triangle, right facing, which is the "run task" button.
To see the run log, on the main Tasker screen, upper right corner, is three vertical dots that will expand into a menu. Click on the "Monitoring" menu item, which will then expand to a sub menu that will have a "Run Log" menu item.
