Do you see a problem in this form? Since spouse' income is 2144, so only this amount is allowed in dependent care benefit (DCB), this is fine. The remaining 856 out of 3000 is lower than spouse' income, it is allowed as well. So in total, the full 3000 is allowed though the spouse has only 2144 income.

Is this a software problem? A bug in the law? Or it is my input issue? This is a simple form and my input is limited, I cannot find a way to workaround this. I think the line 5 should be zero as it is used already in line 19. It cannot be used twice. I am using ProConnect Tax.
