The takeaway is: each private key can generate 2 versions of Bitcoin address, compressed and uncompressed. When you stare at a Bitcoin address, you CAN'T tell whether it is compressed or not, so you have to check the balance of both versions for a single private key.

afaik, each Private Key (Hex Format) can generate 4 valid bitcoin addresses in 3 address formats (P2PKH, P2SH, Bech32)
1 is derived from uncompressed public key, and 3 more from compressed public key

for example,
Private Key Hexadecimal Format: 0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF

Private Key WIF uncompressed: 5HpneLQNKrcznVCQpzodYwAmZ4AoHeyjuRf9iAHAa498rP5kuWb
Public Key uncompressed: 044646AE5047316B4230D0086C8ACEC687F00B1CD9D1DC634F6CB358AC0A9A8FFFFE77B4DD0A4BF B95851F3B7355C781DD60F8418FC8A65D14907AFF47C903A559
