How to attach Schedule K-3s using Turbotax Business version?

I have a LLC I primarily use to make non-liquid investments with my wife (it's a spousal membership LLC).

This is my first year using Turbotax Business and it doesn't seem to support K-3s using the Step-by-Step method? If I go into Forms view, I can select Box 16 (K-3 attached) but it doesn't trigger any issues or errors when reviewing for errors?

I selected those boxes and was still able to e-File? That seems like an error (the amounts involved were all very small, 10-100s of dollars total). Is that why it's not triggering larger issues?
