<reasoning>

Analyze the first sentence

The first sentence is: "The American author, Harper Lee, published only one novel."
The phrase "Harper Lee" is a restrictive appositive because it is essential to identifying which specific American author is being referred to.
According to Punctuation Rules, restrictive appositives should not be set off by commas.
Therefore, the commas around "Harper Lee" are incorrect.

Analyze the second sentence

The second sentence is: "An African grey parrot my pet bird won first prize in the pet show."
The phrase "my pet bird" is a nonrestrictive appositive phrase that renames "An African grey parrot."
According to rules for Appositive Phrases, nonrestrictive appositives must be set off with commas.
Therefore, commas are required before and after "my pet bird" (i.e., "An African grey parrot, my pet bird, won...").

Analyze the third sentence

The third sentence is: "Jerome's brother, a sophomore at my school, is running for student council."
The phrase "a sophomore at my school" is a nonrestrictive appositive phrase renaming "Jerome's brother."
It is correctly set off with a pair of commas.
Thus, this sentence is punctuated correctly.
