Depending on the year of the refinance, you may have written off the points from the prior loan and possibly written off the points on the new loan or amortized them. The rules varied so much over the years. You need to know what you have already written off. But yes, if you have anything not written off, you can claim it now, provided you meet the current points rules. See Publication 527 (2020), Residential Rental Property - IRS for full details.
