Please see the following information from DoninGA regarding adding Form 1095A and 8962 after you have already e-filed:
Here is how to get the form 8962 filled out. Please note: You are NOT going to amend your return and you are NOT going to add a state return. These directions are quirky but will get the job done.
The IRS may adjust your refund once they receive your form 8962.
What if i dont have the option to add state at the very beginning? How would i proceed with fixing this and adding my 8962?
