Turbotax has a warning. if you shared the policy with more than one person contact them for assistance.
you have to specify on the form everyone you're sharing with (the form allows this) Turbotax just didn't bother to program for this. Not only that TT only allows the same % for all months. The actual rules say you can use different %s for different months but in any one month the % must be the same for all 3 items for each person you are sharing.
