Just look at the bottom of the reports page and it will tell you how many you sent, after you see the number you need to count how many denied reports you have. I don't think there is an actual way to see how many accepted reports you have, this is what I do if I want to see how many reports I have accepted. Anyway, good luck on your journey to staff!
Click on the “Accepted” prefix and it will list all accepted reports. Tip: each page has 20, so 20 x pages = total accepted report
