I generally only see an issue in very complex returns. I've got one with about a dozen passive multi-state K-1s and half a dozen active multi-state K-1s, and I will often have one or two states a year that either need a judicious override, or I've got a note in my file that the -1 error isn't material.

If it's a straightforward NR, I would not expect to see any issues other than preparer input or "I didn't bother to read the forms instructions and got an output I didn't expect." Both of which happen to me somewhat regularly, alas.
