Retirement tax questions

Thanks, Susan... I am aware that this is what is supposed to happen and how it is supposed to work.  It is not working.  When I preview, I see nothing and the amount of tax I owed is unchanged when it should be much lower if the overage was included as a credit.  I can't continue (or pay) until this is resolved.  There are other comments about this and a user posted instructions for "Railroad Compensation" but I don't have that.  I just have two regular jobs and one of them took out way too much for social security.
