You're not passing the entire IDCard array, only the first IDCard since you're passing testID[0] to your PrintID function, so you don't have access to all three IDCard's you created in main. No idea what you're trying to do with the index -1 to < 2 in your PrintID function and your 3 integer index fields.

void PrintID(IDCard &idCard) {
 
        std::cout << "First Name: " << idCard.firstName << std::endl;
        std::cout << "Last Name: " << idCard.lastName <<std::endl;
        std::cout << "Phone Number: " << idCard.phoneNumber <<std::endl;
 
}
 
int main () {
 
    IDCard testID[3];
 
 
    testID[0].firstName = "Bill";
    testID[0].lastName = "Smith";
    testID[0].phoneNumber = "111-232-1456";
 
    testID[1].firstName = "Sally";
    testID[1].lastName = "Smith";
    testID[1].phoneNumber = "111-256-1456";
 
    testID[2].firstName = "Billy Jr.";
    testID[2].lastName = "Smith";
    testID[2].phoneNumber = "111-348-1800";
 
    int count = sizeof(testID) / sizeof(IDCard);
 
    for (int i = 0; i < count; i++)
    {
        PrintID(testID[i]);
    }
 
    return 0;
}

void PrintID(IDCard &idCard) {
 
        std::cout << "First Name: " << idCard.firstName << std::endl;
        std::cout << "Last Name: " << idCard.lastName <<std::endl;
        std::cout << "Phone Number: " << idCard.phoneNumber <<std::endl;
 
}

int main () {
 
    IDCard testID[3];
 
 
    testID[0].firstName = "Bill";
    testID[0].lastName = "Smith";
    testID[0].phoneNumber = "111-232-1456";
 
    testID[1].firstName = "Sally";
    testID[1].lastName = "Smith";
    testID[1].phoneNumber = "111-256-1456";
 
    testID[2].firstName = "Billy Jr.";
    testID[2].lastName = "Smith";
    testID[2].phoneNumber = "111-348-1800";
 
    int count = sizeof(testID) / sizeof(IDCard);

    for (int i = 0; i < count; i++)
    {
        PrintID(testID[i]);
    }
 
    return 0;
}
