A loss means no SE taxes are owed, so there is nothing to defer. But we cannot explain how to do it in TurboTax. You seem to be lost on the internet.

You’ve come to a Peer User community for Intuit Tax Preparation products supporting tax preparation professionals using ProSeries, Proconnect and Lacerte , and you may be looking for support as an individual taxpayer. Please visit the TurboTax Help site for support.

Thanks.
