Deductions & credits

Thanks a lot @RaifH  for the information! Really helpful. 

So, I am really confused if shared policy allocation is applicable in our case or not. So, in 1095-A, recipient name is mine (since I did the Marketplace application), covered person is parent and in each 1095-A has different policy numbers. Since each family member has different policy numbers, confused if this shared policy option is applicable. Also, when my parents uploaded their 1095-a in their tax return (for 2021, opened a turbo tax account and uploaded, not submitted), there is no premium repayment shown. They received APTC but since they have very low income there is no repayment showing. This makes me confused whether this is right. I am afraid that, they have no tax due when file but later IRS ask for APTC repayment. Thanks.
