I found this that is helpful. The healthcare.gov site itself also states that if the amount is listed as $0 to use their tool.

I took the below straight from their site.
How to know if your second lowest cost Silver plan information is correct
Look at Part III, column B of your 1095-A, titled “Monthly second lowest cost silver plan (SLCSP) premium.” It should show figures for each month any household member had the Marketplace plan.
The SLCSP premium is incorrect if:
- Part III, Column B has a “0” or is blank for any month someone in your household had the Marketplace plan
- You had changes in your household that you didn’t tell the Marketplace about — like having a baby, moving, getting married or divorced, or losing a dependent
If either applies to you,
use our tax tool (available in late January) to get the premium for your second lowest cost Silver plan.
Use the information from your 1095-A to reconcile
Once you have an accurate 1095-A and second lowest cost Silver plan premium, you’re ready to fill out Form 8962, Premium Tax Credit.
