You should consult a tax expert on this but here is my take. If you have not filed this year yet, I would think yes you can amend your 2022 tax return and claim all of your points paid. However, you must have actually paid some expense out of pocket when closing the loan equal to the amount of points you want to deduct. The expenses you paid didn't have to be specifically for points. Did you pay any expenses out of pocket when securing the mortgage?
Also, after amending your federal tax return, you may need to amend your state return.
