Deductions & credits

Sorry, I was referring to schedule 3  line 9  net premium tax credit.  I entered my 1095-A and it is giving me a refund because my income is below what I estimated, but if I try to increase my income to say 250,000 the amount does not change.  My thoughts is the credit would go away and I would owe money back since my income is higher then I estimated when I signed up for the ACA.
