After you file

From what I can tell, this DOES NOT WORK once the information is entered. I have tried every way I can see. I can edit general information about my business but it NEVER opens up the income and expenses screen so I can MODIFY IT!!!! I want to add one more expense and there is NO WAY TO GET BACK THERE!!!! Or if there is, the explanation of how to do it is TOTALLY UNCLEAR!!!!!!!
