1095-A — Higher income than expected and private health insurance

I had Obamacare until May and then got a higher paying job that offered health insurance.

 

Entering my 1095-A caused my refund to dissolve completely. Is this how the 1095-A works?

 

During the time that I had Obamacare my income was low and thus the credit given to me was valid. Then I got a higher paying job. Does the 1095-A look at my total earned income and nothing else? This seems odd.

 

 

 

Thanks for anything you've got!
