If this mortgage was for your primary residence, then the points were fully deductible in the tax year you obtained the mortgage.
If this mortgage was for rental property or other business property, the points are amortized and deducted over the life of the loan. The fact the lender may have sold your mortgage to another has no bearing on this. You're still required to deduct your points over the life of the loan. Nothing changes for you in that aspect.
