Im having a similar error. It gives error sxhedule M1M and says I must enter grade for 19 year old thats in college. I try to delete him from the form but it doesnt let me edit. How can i delete him from the M1M form and leave my other children. All are under 19 but the 19 year old is in college. I put his schools tax information but in state it automatically put him in the M1M form even tho i put $0 for his expenses on the state question for expenses for him. How can I take him off the state M1M form? Thank you.
