I will turn 70 on March 20, 2017. I applied for benefits and suspended them in Fall 2015. They have sent me a letter, which I received in December 2015, stating that my entitlement date is May 2015 and and my benefit rate is $1883. The letter also states that they will reinstate my benefits at age 70. Later last fall, they sent me a letter stating that my benefit amount was increased by approximately $8 due to income figures from 2015. The result is a benefit rate of $1991. This letter has been misplaced by me.
I wish to start benefits whenever it is best for me. Is there anything I should I do at this time?
No, you shouldn't have to do anything further. Social Security should automatically reinstate your benefits effective with March, meaning that you should receive your first payment in April.
