How do I record self-charged interest on form 1120-S?

I loaned money to my S-corp and we are charging interest as an expense.  I have taken withdrawls from that account.

1. Should I record interest portion of that loan repayment as a expense?

2. Should I record that portion as an income on the K-1 form?

3. How should record this in QBO (expense account or income account)?

4. How should I record this in TT desktop (form 1120-S)?
