What to do if I e-filed without 8832 attached?

Hello.

I changed my business structure from sole LLC to partnership LLC last year. My business agent told me that I don't have to do anything with the State but keep my internal record.

So I sent form 8832 to IRS in November but didn't receive the determination yet which possibly means IRS might not receive it (I didn't use certified mail). 

And I filed tax return with this change: 1065 for partnership LLC (e-filed without 8832) and included Schedule K for personal filing.

I just learned all this went wrong. How can I fix this situation?
