Update... (I'm the OCD guy who wants to do it right - not just fudge with a $1.)
There is a bug in TurboTax because if you enter $0 for meal expense in Sched C, it triggers the CO state to require you to enter >0 for this field.
To fix, go back to your Federal and look at all Sched Cs and K-1s. Hint: Use Forms and looking at each K-1 and Schedule C for "meals". (I don't know of a way to search the forms for "meals".) I found a Sched C that carried over $0 meal expense from previous years (in Supporting Details breakdown). I deleted that (go to the Easy Step and verify the field is empty to be on the safe side - if not, you can delete it there).
Warning: I had to delete the state data (File->Remove Colorado Data) and then go through the prepare state data again as the previously propagated meals did not update after the I changed the Federal forms.
