I paid taxes, penalties and interest in 2017 from my 2016 taxes how do I account for this on my 2017 tax return?

My 2016 tax preparer forgot to include moneys that were withdrawn from my retirement account.

Your tax preparer made a error, so should cover those expenses.

You don't.  It doesn't go on your 2017 return.    Each year is separate.  If you paid any state tax on it you can deduct state taxes actually paid in 2017 as an itemized deduction.  But just the tax, not any penalty or interest.
