thanks @ThomasM125 in this case it makes sense that I received a 17k credit on 28k paid but then.
but then the question is why it doesn't cover whatever this additional income increased in the taxes I owe?
could it be that the credit is calculated on the US to be paid on the amount with the amount by itself so for example 10k but when the amount is added the other taxable income then overall percentage is higher and therefore results in a 14k tax increase and not 10k?
