Turbotax Maryland form line 2, "Tax-exempt interest on state and local obligations (bonds) other than Maryland"

I am attempting to use Turbotax Premiere to edit my Maryland state form to report "Tax-exempt interest on state and local obligations (bonds) other than Maryland" -- I know the amount I need to enter on this line, have figured all that out based on my 1099-Div -- but I CANNOT figure out in Turbotax how to get this entered correctly.  They sure do not make it easy!  Can anyone help?
