In 2017 I filed a 5329 and paid a penalty, where do I report tax penalty paid in 2018?

An early withdrawal penalty from a tax deferred retirement account for a prior tax year is not reported on nor deductible on a federal tax return.

Thank you. It wasn't an early withdrawal. I forgot to withdraw my 2017 RMD. I withdrew the money in April 2017, filed a 5329, requested a waiver and was denied. I paid the penalty in April 2018 with my 21 taxes. Now, that withdrawal is included with my 2018 RMD on my 2018 1099-R.  But there is nowhere that I can find to report the tax and penalty I have already paid on the 2017 portion of the 2018 1099-R.
