Sorry, I missed the part about the second K-1.

I don't remember if there are any 'proper' ways to do it, but here are a potential couple of work-arounds:

1. If there are no passive activities on the 1040, you could check the Real Estate Professional box on the information worksheet to make the rental non-passive.
2. I think checking the "recharacterize" box on the rental K-1 (right by Box 3 where you entered the rental income/loss) would do it.  However, if I remember correctly you need to be careful with that because in some cases it doesn't quite do it (I don't remember the specifics though).
