Put the section J info on the K-1 that best fits the main business function. In other words, if it’s a real estate rental business, put everything on the K-1 with Line 2. It’s a primarily a regular business, put it all on the K-1 with Line 1. It really doesn’t matter which one it goes on, you just want it entered only once, on one K-1 or the other. You’re doing this to solve TurboTax’s entry glitch, not the IRS’s.
The reason to put it in the K-1 most like the main function of the business is that in future years you may wind up with only a Line 1 or a Line 2 entry and won’t need that extra K-1.
