To obtain the monthly payment you need to divide by 12 which you did. With an average 5 years highest salary of $\$30,705.17$ and 33 years of service I got a monthly payment of $\$928.83$ as you did. But what about the units? The figure 30,705.17 is in the units of dollars per year so the calculation for the annual pension payment is \[1.1\% \times 30.705.17 \frac{\mbox{dollars}}{\mbox{year}} \times 33 \mbox{ years } = \$11,145.98\] which, divided by 12, is $\$928.83$ per month.
