I am a bitcoin newbie and I have created a so-called wallet, but I can't seem to find any instructions on how to actually put money into it so I can make bitcoin payments. Can anyone clear this up for me, please?
Almost all wallet have a button "Receive"
Then you will see your Public Address, which you should transfer your funds to.
As mocacinno said, be sure you are using a safe wallet. Which wallet are you using?
