Did you go up to Section C and allocate gross receipts or farm income or rental income to Iowa.  This new partnership return is full of bugs.  The keep sending out new updates but when you enter an Iowa partnership, Vegas would get jealous with all the red lights.  Just when you figure out how to fix something another update comes out and you start from scratch.  I finally got all S-corps to file today.  But I might wait to see next update before I just go in and override each line to be able to transmit partnerships.
