@johnmatthews2701 - 'miscalculation' means that the math (additions, subtractions, multiplications, divisions) is incorrect. 

 

but if the numbers entered are incorrect, then of course the result is incorrect, even if the math is correct 

 

from what I've seen across 100's of posts on these boards, the math for the Recovery Credit and the Child Tax credit is correct. 

 

But if the user doesn't enter the amount they already received for these benefits correctly, then the result is incorrect even if the math is correct.

 

TT is responsibile for the math

the user is responsible for the numbers entered
