if someone else owns your loan now, that doesn't change the terms of your loan. You can ignore that event, unless you get two 1098s
No, not as a deduction on your current year return.
Points paid on a refinance are generally amortized over the life of the loan, not deducted in the current year and that should continue until the loan is paid in full.
When a loan is sold from one lender to another, the borrower doesn't generally have out-of-pocket closing costs again, the loan stays the same but it is just paid to a different lender. So, no, your points from the refinance were not paid off when your loan was sold to a different lender, and especially not paid off by you.

Can I deduct points on my cash out refinance
I didn't get a 1098 for the points I paid I just received a 1098 from the new leader, however it didn't show points and I wanted to take the deduction for the points.
The same points from the refinance with the other lender still apply to the life of the loan. When it is points paid at a refinance, then you must remember to amortize them over the life of the loan. They may not report them on Form 1098 from the new lender.
