Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
A K-1 form is used to report a partner's share of income on form 1065 or to report the distribution of income from a trust from form 1041
Schedule K-1 is not something you will prepare unless you are a part owner of a business. It will be prepared so that you can claim your portion of income and expenses on your tax return
