Report owner distribution for passive rentals on Schedule E?

[Olivia Piper]

I own a couple rental properties in a single member LLC. If I need to withdraw some owner's capital, which as far as I understand is not a taxable event, should I report it in Schedule E on tax return? If yes, how do I report it? If not, where should I keep a record of that event in my bookkeeping? Thanks in advance for your suggestions!
