Business & farm

Thank you @AmeliesUncle @Carl @M-MTax for the promote reply! Another question is: all my business income for A LLC is from B (schedule K1, I know A is a disregarded entity, but K1 from B still has firm A's name and number on it (as well as my personal id)). For the business expenses, for example the computers i purchased under A LLC, should I deduct it as B's expenses ? (since I don't need to issue myself K1 from A, turbotax think there's no income from A)

I'm confused how to report the business expenses. Do I even need to mention firm A at all ?
