As the link I gave you shows, the IRS Instructions tell you to use Line 11 if (1) column A of the 1095-A is all the same for the entire year and (2) column B of the 1095-A is the same for the entire year.  And it says to use 12-23 if they are not all the same.  So you just need to make them 'not the same' to trigger lines 12-23.
