After you file

Thank you trying to help but the answers are still not lining up.  Here’s one example, for CO, my income was 3194.  In the Calculation of Credit  Lines 26 & 26 read 3179 and Line 28 reads 89.  I owe CO $9.00. How are these numbers calculated?  I cannot figure it out but, then again, I’m no math or tax whiz.  The numbers are filled in for CO and MT but not MN (We once had reciprocity but no longer.). Thanks for trying to help.
