First the Sch A is not fully functional and will not be until 1/10 at the earliest so you may just need to wait a while. Also you should only enter the 1095-A form and the premiums should flow to the Sch A automatically. Also on the 1095-A form you must have an entry in column B even if the 1095-A form doesn't have it filled in ... log into the ACA Marketplace to get the amount you need to enter ... 2023 forms and tool are not yet ready...
