I have already done what you are suggesting. The program still wants to treat the amount in box 11 as a state income even though boxes 15-18 are blank. the only thing I could do is override the amount that the program placed in income from other states. That prevented me from being able to file my state tax return electronically. When I tried to get it to ignore the error, it went into an old fashioned "do loop" and went back to the screen to suggest that remove the override.
