Bitcoin is prompting me for my wallet address.
Can you clarify where you are purchasing bitcoin from which is prompting you for your withdrawal address? If you are using "bitcoin.com", be aware that this is actually a scam site designed to trick you in to buying a coin called BCash (BCH) which is not bitcoin. Make sure you are actually buying bitcoin (BTC).
I have installed the electrum wallet but cannot find this information. Anyone who is willing to help?
Have you created an Electrum wallet yet? You need to hit the button "Create New Wallet", choose a name for your wallet, select "Standard Wallet", "Create a new seed", and then write down the 12 words your are given on a piece of paper which you still store somewhere safe. Do not be tempted to take a picture or screenshot of these words or save them in a document, email account, cloud storage, etc. Write them down on paper only. Confirm them on the next screen, and then choose a password to encrypt your wallet. Once you've done all that, you can click on the tab "View" then "Show Addresses", and pick any address labelled "receiving".
