More details - If You Change Your Mind
Unexpected changes may occur after you make your decision about when to start your Social Security Retirement benefits.
If you are receiving Social Security Retirement benefits and you change your mind about when they should start, you may be able to withdraw your Social Security claim and re-apply at a future date.
However, if you change your mind 12 months or more after you became entitled to retirement benefits, you cannot withdraw your application.
