I am the only owner for my llc, no partners involved for 2024. on section "about your business" what do i select for partnership tab?

Is your LLC a Single Member LLC?   If you did not elect it to be a S corp then it is a disregarded entity and you file it as a Sole Proprietor on Schedule C in your personal 1040 tax return.   If it is a S Corp it goes on form 1120-S not a 1065.
