Using Turbotax Business to File 1041 for 4 Trusts, How many state returns are included in price?

My purchase of Turbotax Business allows me to file four separate 1041 Federal returns. I am filing returns for 4 Trusts that were set up for my grandchildren. Does the purchase of the state filing for one also cover the other 3 returns, or will I need to pay the $55 fee for each return?
