The rule of the FV (future value) is

P is the value each month
i is the rate divided by 12 month
n = number of years x 12 months
Since the deposit every month is $1643, then

Since the annuity rate is 4.5%, then

Since the number of years is 11 years, then

Substitute them in the rule above

The account will have $279,959 after 11 years to the nearest dollar
To find the interest subtract $1643 x 132 months from the FV

The amount of interest is $63,083 to the nearest dollar
