The pension your receive was not based on earnings covered by Social Security.
A pension based on earnings not covered by Social Security can affect the amount of your Social Security benefit.
This is called Windfall Elimination Provision by the SSA.
Before 1983, people whose primary job wasn’t covered by Social Security had their Social Security benefits calculated as if they were long-term, low-wage workers. They had the advantage of receiving a Social Security benefit representing a higher percentage of their earnings, plus a pension from a job for which they didn’t pay Social Security taxes. Congress passed the Windfall Elimination Provision to remove that advantage.
