Yes if the contributions were for 2017 and you removed them with the earnings to avoid the excess contribution penalty then it is taxable in 2017 and you will have to amend your 2017 return if you didn't include it already when filing the original return.
You will not need to include it on your 2018 return unless it shows tax withholding in box 4. TurboTax should ignore a code JP 2018 Form 1099-R other than to remind you that you should have already reported this on your 2017 tax return.
From IRS Pub 590-A:
"For purposes of determining excess contributions, any contribution that is withdrawn on or before the due date (including extensions) for filing your tax return for the year is treated as an amount not contributed. This treatment only applies if any earnings on the contributions are also withdrawn. The earnings are considered earned and received in the year the excess contribution was made."
