I sold a house in 2018, paid lawsuit fee for this sales in 2019. Can I claim this legal fee in 2018 tax return? If not, how can I claim this legal fee in 2019 tax return?

Legal fees associated with the sale of your home are generally included in deductible sales expenses if incurred before the sale is finalized.  However, a legal fee paid after the sale would be personal legal expenses and non-deductible.
