Aggregate mistake

I aggregated 2 rental properties together. I now realize that was incorrect. I want to un-aggregate them but they option to do that does not appear anywhere during the step by step process. I have tried to delete (using forms - delete) the form 8995 as suggested in another discussion of this issue but the form does not delete not matter how many times i try.

 

I have read elsewhere in that i need to start my taxes over to un aggregate the businesses. I can find no way to do it after significant effort and research. Please let me know if there is a way to do this, mu taxes are almost complete and it was a lengthy process

 

I am using Premier CD (downloaded)

 

Thank you
