Deductions & credits
Enter your 1095-A as received. When you state the Allocation Percentage of 0% in the interview, TurboTax will do the calculations for you on 8962. You don't need to make any adjustments to the amounts on the form itself.
If your form only has amounts in months from January through August, leave the other areas blank. If it has amounts in months for January through December, but you only shared January through August, you should still state the policy months as being January through December, as the 1095-A shows.
I tested this in TurboTax Desktop by indicating 0% and entering 1095-A data for months January through June. I received a window stating 'You Maximized your Insurance Discount Last Year', with 'Total Credit you qualify for' as $0, 'Minus what you got in advance' $0, 'Remaining Credit on this Return' $0.
My Form 8962 has Family Size 0 on Line 1, Line 9 has box checked' Yes', and in Part IV, Line 30, more 0's. This is correct, as the IRS just wants to see Form 8962 and 1095-A in your return and you neither owe or get a refund with a 0% allocation. You could delete your 1095-A and 8962 and step through the interview again.
