can one find an accidentally created change address and restore the lost coin? that is what I think I did!
No, not with electrum. It does it automatically for you.
Its easier to help you if you answer the questions asked.
Where should the coins go (as in: to which address)?
How much coins did you send?
Which electrum version do you use?
Is electrum connected?
Did you try to send the coins to a person or a service?
Did the recipient confirm the address?
Which wallet does the person reciving the coins use?
Which service did you try to send to?
