Sorry once you pay or register you can't clear. You will have to go through and delete or change each item. Why can't you efile? What is the reject code? Maybe we can help you fix it.
Thank you for your help! Unfortunately, it does not say any codes. I am attaching the screenshot of the message.
I did check the "review" section, it does not mention any forms that can not be E-file. It just shows the "correct" checkmark and says everything looks fine and takes me to the filling section. In the filling section, I get the attached screenshot message.
