I have the same issue - the $150 credit is there - it's on Schedule 3 - it even subtracts properly on page 2 of the return - but then it goes off

The total tax is $7,094 - total credits (including the $150) is $1,795 - leaving the tax liability at $5,299 - but according to Pro Series - if you subtract $5,299 from the withholding of $8,818 you get $3,369, not $3,519
