Deductions & credits

Thanks, but I feel it may be a little trickier (and more random).  We file jointly and take the standard deduction, but I could not get the correct number in the little box. We wound up having only $425 in cash deductions this year, but TT kept refilling with $300 no matter what I did.  I have gone doggedly through several iterations of solutions, including the solutions in this posting to the point that I'm not sure what finally worked.  I never got back to the ACA script, which I remembered from last year, but when last I saved, closed, and reopened, it stayed correct.  I think this is an area TT needs to take a look at.
