If there is an incorrect form 1095-A with zeros or blanks in column B (SLCSP) per the instructions from Healthcare.gov, you are to use the correct amount, not zero for this line.  When you do this and all of the entries in column A & B are the same amounts, it automatically answers the question on form 8962, line 10 to “yes” and only uses annual totals on line 11 of this form.  However, the IRS is looking for the monthly information on lines 12-23 and will send a notice if it is not there.  Please save us the trouble of responding to an IRS notice and give us a way to override the answer on line 10 to “no”.
