Irs interest income

[gcalixtro05]

I filed a tax amendment last year for 2014 & 2013, I received a refund but that included some interest from the IRS, I think I need to pay taxes for those interest I received, but I can't find the documentation where the interest amount was shown, how can I get a copy of these documents from the IRS?

Do you know the amount?  You should have got a 1099 from the IRS.
Enter interest from the IRS like a 1099Int and put the amount in box 1.  
Enter a 1099-Int  under
Federal Taxes tab
Wages & Income
Interest and Dividends
Interest on 1099INT - Click the Start or Update button

Put the interest amount in box 1

If you can't locate your 1099,  you can determine the amount of interest income by comparing the refund you received to the refund amount reflected on your 1040X.  This difference will be the interest earned.
