Why is my iPhone 14 Plus camera not showing Macro mode?

I have an iPhone 14 Plus (iOS 18.5). My camera doesn't focus on anything unless it's at least 8" away. Anything closer and it's blurry. Even if I tap on the image of the object to auto focus on it, it remains blurry. I heard that my iPhone has macro mode but when I watched a video explaining it, the flower icon didn't appear on my screen.

Another post on this forum said I should go to Settings > Camera > Formats and enable Macro Mode. But in the Formats window, there are only two choices: High Efficiency and Most Compatible. No choices for macro mode.

Does my iPhone not have macro mode? Am I doing something incorrectly? Thank you for your help.
