Efile was rejected, so I used last years account, now I have 2 accounts that are exiled and only want one of them. What do I do?

I couldn't remeber last years sign in info, so I made a new account,filed and was rejected due to the age. Figured out last year account info and just went from there and filed with that account. Now I have w accounts 1 rejected and 1 pending. Whats going to happen? How do I cancel the rejected?
