Hello @Mike9241 and others
I have few questions regarding K3 if you don't mind helping me here.
Very first part of Interview is asking foreign source in Line 24. Lets assume my K3 looks like this (example)

Q: I am assuming I will enter either zero or nothing in first part of K3 interview screen where It is asking me enter column B,C, D, E, F and G of Line 24 as there is no foreign source income?
Now deductions part looks like this

In next interview it is showing Interest Expense total as 1500 but question is it us source or foreign? Software automatically add it into US source.

Thanks a lot for your help.
