No, don't hold her nose to it and it isn't necessary to tap her butt either. A firm NO is all you should need...scoop her up and place her outside. Tell her to potty outside. If you have figured out when she usually goes...then that's when you should have her outside....don't wait for signs from her. If you happen to see the signs she needs to go...sniffing and getting in a poop position...take her out immediately. She might not go the minute you take her out, it'll take some patience on your part.
