I understand what you are saying, but I'm sorry that I don't have the solution. It makes sense to me that you would enter 0 on line 9, but I don't know if that is correct.

Maybe you can help me. I'm trying to determine the proper way to enter the $10200 UCE on 104PN since the taxpayer excludes it from federal, but it's taxable in CO. If on the federal portion, line 18 I entered -10200, to figure taxable income, what should go on the CO portion, line 19, is it 0 or -10200? Then on federal, line 26, I entered 10200 back in to figure MAGI, what goes on CO portion, line 27, is it 0 again or 10200?

Thank you
