I fill in the information exactly as it is on my 1095-A, but TurboTax won't let me continue.

 I only had coverage for one month and I did not use my $154 premium tax credit.  The Monthly Premium Amount of Second Lowest Cost Silver Plan was 0 on the 1095-A, but I looked up what it is and filled it in on TurboTax. The Monthly Advance Payment of Premium Tax Credit is also zero and TurboTax will not accept a blank box or a zero.
