One of the reasons I switched to entering the K1 loan payment to 13zz from 20zz (where the loan payment was listed) is because the TurboTax online version would not allow me to type in (override) the Turbo tax input system. I was in formed, however, the desktop version does allow this. If this is true, go to the tax form (pre submission). Go to Section E, Page 2, Part II, Line 28, column i (Nonpassive loss allowed). Enter the loan interest amount and the description. (Your non passive income from you K1 should also be listed in this section under column k).
