Great, that fixes that part.  To populate a different Iowa NOL for Line 1 of Part II, you can do that in the Iowa Net Operating Loss section of Screen 15.

As to Line 4 of Part II, in the instructions to the 124, it says it comes from line 4 of the IA1040 (without accounting for the NOL adjustment).  As far as I can tell, Lacerte is doing that.  I just looked at one and if I take the IA1040 line 3, then go to Iowa Schedule 1 and make the adjustments except for the NOL lines, it comes up with the same number as on the 124 line 4.

So maybe Lacerte is doing it right according to instructions?  BUT, I really question if this is Iowa's intended outcome.  I have a client with a large NOL.  His line 4 income without the NOL adjustments is negative, so $0 on 124 Part II line 4.  The effect is $150,000 of federal NOL being added to income, and no Iowa NOL being deducted.  So he is paying Iowa tax on $150,000 NOL! Maybe that's right but it feels very wrong. Of course this is a March 1 farmer. 

I sent an email to IDOR, but they probably won't answer fast enough.  I might try calling.
