If statement in python not printing

I am working on an assignment for school, and this program is SUPER easy, but my if statement isn't working properly. Does anybody know why? Here is the code:

letter = input("Name one of the most common letters in wheel of fortune puzzles: ")

if letter == "r":
    print(letter, "is one of the most common letters!")
if letter == "s":
    print(letter, "is one of the most common letters!")
if letter == "t":
    print(letter, "is one of the most common letters!")
if letter == "l":
    print(letter, "is one of the most common letters!")
if letter == "n":
    print(letter, "is one of the most common letters!")
if letter == "e":
    print(letter, "is one of the most common letters!")

else:
    print("Incorrect!")
    letter = input("Name one of the most common letters in wheel of fortune puzzles: ")


input("\n\nPress the enter key to exit:")
