I have to report taxable interest paid to me from irs in 2016. where or how do i file that?

Interest Income (even from IRS) has to be reported on your return.

To enter this in TurboTax, 

Go to Federal Taxes

Wages and Income

if not listed click on show all income

Then go to the Interest and Dividend area

and click start

I received statement from internal revenue service that do not indicate any form number. Turbotax is asking for that. how I enter it correctly?

IRS interest 1099 form probably only says 1099 (rev. 9-07) on it.  The IRS EIN # on  it is 38-1798424.

Enter interest from the IRS like a 1099Int and put the amount in box 1.  
Enter a 1099-Int  under
Federal
Wages & Income
 Interest and Dividends
Interest on 1099INT - Click the Start or Update button

Put the interest amount in box 1
