On Form 1095-A, how do I determine the SLCSP for a partial month? Is it simply the monthly amount prorated for the applicable number of days in that month?

Can you clarify why you need a partial month SLCSP?  Thanks.  @greg-mellstrom

Two 1095–A forms due to change in number of people covered and plan change mid-month. Thanks.

What do your two Forms 1095-A show for the month in question? Generally, you should enter the amount from your form. 

It is not a problem to have more than one Marketplace insurance plan You can enter both Forms 1095-A in TurboTax.

• Add the information for your first Form 1095-A
• At the "Here's what we have for your 1095-As" page, click Add Another button, and follow the steps to enter your second form.

From Healthcare.gov:

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.

Enter the SLCSP from just one Form 1095-A for the duplicated month, as stated in the Instructions for Form 8962. If you believe one of the forms is incorrect, you could contact the Marketplace, though the instructions state this isn't needed.

Thanks, but the responses do not address the question posed. The query was how do I determine the SLCSP for a partial month? The SLCSP column is blank on each 1095-A. Can the SLCSP show a partial month amount where coverage was in effect for a partial month (which is what the premiums reflect)? If so, how do I calculate the partial month SLCSP?

Please read this part of the instructions for the form 1095-A (these are the instructions for the marketplace creating the 1095-A, not for you).

Go down to the phrase "leave column B blank" Does this describe your situation (i.e., the entries are supposed to be blank and not prorated)?

[greg-mellstrom]

Had two people covered under the first policy through March 30. Column A for this first policy shows the monthly premium for March prorated for 30 of the 31 days. Column B is completely empty for all months on this 1095-A.
Had one person of the previously referenced two people covered under the second policy beginning March 30. Column A for this policy shows the monthly premium for March prorated for 1 of the 31 days. Column B is completely empty for all months on this 1095-A.

If I use the SLCSP for the first policy for the entire month of March, it does not align with the 30-day prorated monthly premium in Column A for the first policy. 
If I use the SLCSP for the second policy for the entire month of March, it does not align with the 1-day prorated monthly premium in Column A for the second policy. 
Should I prorate each policy’s SLCSP premium for the month of March to align with the Column A prorated amounts for each policy or is there a better way to determine this amount? Leaving one blank or zero due to termination or enrollment that occurs on a date other than the first of the month seems illogical and misaligned with the Column A amounts. What do you advise?
