Retirement tax questions

Thanks, @Joopkins 

 

"My accountant manually fixed the incorrect amounts (lowered my social security income to the max, and my social security taxes withheld to the correct max) and submitted my taxes as such using his pro intuit software or whatever he uses."

 

I don't see a section in my 1040 or any other form to do this manual fix. Could you tell me where do I change this?
