I'm sorry but I don't know what you mean by "inputs". So, if I "Clear Unconfirmed", the BTC should show up in my wallet. Then if I move that BTC to another wallet, (and then back), that should consider it spent or "respend"?
ELI5 I guess... Thanks for your help!!!!

Bitcoin transactions work by creating outputs and spending the outputs created by a previous transaction. The spending of outputs is called an input in a transaction. You have a transaction which spends some inputs and creates outputs for people that you now don't want to pay. In order to prevent this transaction from ever confirming, you must spend those inputs in a different transaction and get that transaction to confirm. By doing so, you will invalidate the original transaction since you can't spend inputs in two different transactions and have both confirm. That is the only way to guarantee that your Bitcoin actually returns to you.
You can just send the Bitcoin to an address in your wallet. To ensure that you spend the right inputs, you should use the Coin Control option and find and select the inputs that you spent in your original transaction. They are all labeled by the transaction id that created the output you want to spend and the output index (which number output it is). This will ensure that you spend the right inputs.
