[Can't generate Tax Return because of ON-BEN warning! (not claiming ON-BEN)]

Further to my first reply to your post, you will have to go to the ON-BEN sub lines on the interview list and delete the two lines where there is either a little garbage can beside the application and the tenant of home owner declaration one just doesn't do it.

Just go the the menu of your interview and go to the icon of the ON-BEN and beside the form there should be a little garbage can just click on it and it will ask you if you want to delete.  Just say yes and you should be done unless you need to do same with the Tax payer or Tenant declaration.  Then do the same and your program should generate a tax return after that.
