Do I get any credit for points and closing costs paid when I did a refi on my home loan? And if so, where and how do I enter this info?

On a refinance, the points must be spread out over the life of the loan (i.e. 1/360th of the points for each month you made payments on the refi in 2018 for a 30 year loan). TurboTax should calculate this for you but double check.

Closing costs are not deductible.
