State tax filing

Hi @DMarkM1 ! 

Sorry to bug you on this again! 

I was just reviewing my TTax-generated Colorado taxes and noticed the "Federal Deduction addback (see instructions)" being 11,700. Last year I did my taxes through a tax preparer and it was 0, so I started Googling to see what that number is and found this thread. 
I've run the math according to the link you posted (https://tax.colorado.gov/sites/tax/files/documents/ITT_State_Income_Tax_Addback_Feb_2024.pdf) 
and from my math, the amount should be 0. 

I subtract 10000 - 141630 - 3779 - 302 and is clearly negative, so 0. 

Then Line 8  is (33 489 (itemized deductions) - 27 7000 (filling jointly) and I get 5789

Line 9 is the smallest of 5 (0) or 8 (5789), so it should be 0, yet I see 11700.
