I'm fairly positive of how to do the 11 journal entries for August. What I'm not sure of is the adjusting entries in instruction step 12. The results, as noted in the hint at the bottom of the instructions, should be Cash balance $2,020 (which I have); Trial Balance $30,700 (which I have), Adjusted Trial Balance $32,580 (which I have, but possibly for the wrong reason), and a Net Loss of $530 (which I'm off by $200). I currently have a net loss of $730.
