Am I Out Of Luck?
In August 2014, having reached my FRA, my disability benefit automatically converted to a retirement benefit. I immediately applied for spousal benefits and filed form 521 to withdraw my retirement benefit as if I had never filed for a retirement benefit thus allowing me to accumulate delayed retirement credits. Upon request, I payed back the one retirement benefit check I had received. So far, everything had been confirmed in writing as expected. In May 2018, I applied for my retirement benefits to start at age 70.
