Two 1098s, where should the points go or can I deduct them all?

I bought a new home last year, and it was financed through the builder (Lender A). It's a smallish loan, well under the 750K cap, and I have around $5K of points paid that shows up in box 6 of the 1098.

 

Lender A sold the loan a couple weeks after closing to Lender B. Lender B's 1098 says nothing about points.

 

When filing taxes in Turbotax, should the points be logged under Lender A, Lender B, or both? And do I amortize the points over the life of the loan, or deduct them all this year, since I'm using a different lender going forward?

 

Assuming I only amortize the points under Lender A this year (since they are on their 1098), what will I do in the following year, when I only receive a 1098 from Lender B?
