Retirement tax questions

@chewkong interesting that the diffence is EXACTLY $2700.... there is an old math trick from the bygone era of data entry (which unfortunately the IRS still does on paper filed returns).....when you add up a column of numbers twice (which is what we have here - your return  is one column and the data entry is another column) and the sum of the digits in the differience equals "9", there is a key punch error.  

 

So 2+7 = 9......key punch error!!!!!!
