Form 1095-A Column B Question

In 2021, I paid full premium for 7 months (January - July) and received APTC for 5 months (August - December}. My 1095-A shows SLCSP data for the 5 months for which APTC were received, and zero for the 7 months for which the premiums were paid in full. I looked up the Tax Tool and got a SLCSP number that is different from the one that is partially listed on my 1095-A. I wonder which of the SLCSP numbers do I use to complete Form 8962. Please help.
