You can access the 8962 on the IRS website, you only have to wait till late February if you want to ammend your return electronically. I do caution that filling out the 8962 is definitely a process, it's confusing and the directions are absurdly hard to comprehend for people who aren't in accounting. Ammending it electronically is easier because you'll just enter the 1095 like TT SHOULD have prompted to behind with, but it will further delay your total processing time.
