How should I modify Form 8962 to account for the period I was out of the country?

My filing status is married filing jointly.

I purchased covered California insurance for the whole year but I was out of the country for 29 days in January and my wife whole month in January and February.

Assume in 1095-A, all columns of A (Monthly enroll Premiums) in Part III are 1000, B (SLCSP) is 1200, and C(Monthly Adance Payment of Premium tax credit) is 900.

When I fill out 8962, which column on line 11 should I adjust?
