Retirement tax questions

on the adjust Federal Dividend Income page, it says Enter any PA adjustment...it gave my Federal total Ord Divs, Capital Gains and yeah, for some reason , U. S . Obligations, so I went and divided out how much was done while I was living in PA  and how much while in TN.  I figured they listed the U.S. Obligations for a reason though have no idea why so I did use the portions of those  in the adjustment amount.   

 

So that means part of their total for PA after adjustments  is US Obligations. Since I already filed, should I amend my return and how do I account for the fact they put my entire year's US obligations in there?  Don't want to be paying extra tax!

 

Thanks!
