It forces you to enter self-employment (eg. 1099 income), which is not correct. I have only K1 income from my LLC, through which I made direct solo 401k employee contributions (so it's not on my W2). This should be allowed as only the Employer contributions are deducted on the K1. TurboTax support was of no help, after 90 minutes speaking with them. Anybody found a solution?
