retired in 2005. have worked pt since and paid in ss. should I review my benefits
I assume you mean that you're drawing Social Security benefits and have worked since you started drawing. If that's the case then your earnings subsequent to filing could cause a benefit rate increase, but only if your earnings in one or more of those years was higher than one of your highest 35 of wage-indexed earnings years used to compute your original benefit rate.
If you did earn enough to increase your benefit rate in any of the years after filing for benefits, Social Security should have automatically increased your rate without you needing to do anything. But, you could contact them and double check if you want to.
