My husband died in 2001. His income for last 20 yrs averaged $225,000.plus a year. The 15 yrs. prior were good earning years but not as much. He received SS for a year before his death. Social security said they didn't have record of 3 of his earning years. Could this have an effect on his SS check? If so, then my check (I get his SS) could be effected also. I receive much less than most of the people I know. Is there a way to check if he received the correct amount? Thank you for any help you are able to offer.
