where and what would be reported on a 2018 tax return?

The Cohens have a $43,000 long-term capital loss carryover from the prior tax year. The Cohens received a New Jersey state income tax refund of $400 in May of 2018. The Cohens received the refund because they had overpaid their New Jersey state individual income tax in 2017. On their 2017 Federal income tax return, the Cohens itemized, and deducted and received a tax benefit for all state tax income taxes paid in 2017
