On a refinance, points must be spread out over the life of the loan. Supposing you paid $3000 in points and refinanced in June. Spread out over 300 months, that's $10 per month, which would give you a $60 tax deduction for 2020, which would give you an additional $10-$20 refund if you amended.
You can still deduct your 12 months worth of points in 2021 (and future years) even if you don't deduct them in 2020.
