How can I cause Electrum to forget a transaction?

RBF? I am not sure what that is, so it is unlikely I had it enabled. I guess I was confused, I had always used the suggested fee and it's always panned out well before, anything I can do?
Worst case scenario, is there a way I can recover the coin or resend them?

I have a transaction sitting in pending that has not yet been confirmed, going on 24 plus hours. Tx was 1 Btc, fee was .00001 btc. Correct wallet address. The sending address was an Electrum wallet on a portable TAILS install with persistence enabled. I don't have access to the TX number right now, but I can provide it. My question is, if the transaction stays unconfirmed, will the coins be returned to my Electrum wallet?
