I keep getting .17 which should be 17%. Need assistance with what is wrong in my calculations.

Last year Janet purchased a $1,000 face value corporate bond with a 12% annual coupon rate and a 20-year maturity. At the time of the purchase, it had an expected yield to maturity of 12.23%. If Janet sold the bond today for $1,026.84, what rate of return would she have earned for the past year? Do not round intermediate calculations. Round your answer to two decimal places. 17 %
