Thanks. This helped. I still consider this a bug in the program as I had $0 in meals on a Sched C, but the CO state wants a positive number...
I found a $0 meals expense in a Sched C that was carried over from previous years (I assume because it had supporting details). I cleared that entry.
I DID have to delete the Colorado state return and start over for the entry to be cleared (and I was careful not to enter anything in the business meals addback entry). I now get no errors.
