I have been making irs and state payments from a previous error on my 2015 tax return. Where or how do I end these payments on the 1040?

the irs payments are not deductible

Really??, the Federal tax payments are not deductible?? 

But only the state are deductible?  Did I understand you correctly?

The state tax payments would be an itemized deduction on the Federal return.

These payments can be entered as follows:

To enter estimated taxes paid (Federal, State, Local)
•    Click on Federal Taxes (Personal using Home and Business)
•    Click on Deductions and Credits
•    Click on I'll choose what I work on (if shown)
•    Scroll down to Estimates and Other Taxes Paid
•    On Other Income Taxes Paid, click on the start or update button

In some states the Federal payments can be deducted on the state return (limited number of states do this).
