Retirement tax questions

5,500 is the excess amount held. Job A  witheld 9114, Job B witheld 5558.  

 

2 seperate FEINs. 

 

I'm on hold with the IRS (hour 5) I'm trying to understand why.  The note said:

We changed the amount clamimes as excess social security tax or tier 1 RRTA withheld on your tax return becuase you incorreectly calculated the excess amount. 

 

There is no other data point provided on form CP11 than that.  

 

Thank you.
