The main thing is to say where you want to transfer these bitcoins to your wallet. Did you use an exchange like Coinbase to buy Bitcoins? Or someone else is trying to send to you bitcoins?
Bitcoins addresses start with only 1, 3 or bc1. If it starts with 2, m, n or tb1. It is an address of the testnet blocknet . It has no commercial function. Some people may try to cheat by saying that they will send Bitcoins and actually send Bitcoins testnet.
Thank you for sharing, I know today that BTC addresses have these distinctions.
