Can I deduct federal tax paid in 2017 via withheld refund of my 2016 return?

Do you mean the 2016 Federal Tax Refund was applied to the 2017 federal taxes when you filed the 2016 tax return?

No. My 2016 Federal Tax Refund was applied to my outstanding 2015 tax obligation.

Federal taxes owed and paid for a prior tax year are not reported on nor deductible on a federal tax return.

Sorry no.  Each year is separate.
