No - It is not necessary to enter the amount in schedule K-1 box 14A in your Missouri tax return.
Box 14A simply indicates that the income listed is self-employment income. It is already included in the Box 1 amount.
If you received a MO K-1 in addition to the federal K-1, then you would compare the two forms and enter any differences as additions or subtractions on the MO return.
