I'm going to page @Rick19744 for this but, in short, the property will go in to the LLC the same way it comes out of your MFJ reporting on Schedule E; there will be no recognition of gain.
In TurboTax, you will have to show the property as being disposed of other than by sale in order to stop depreciation and remove the property from your 1040 (Schedule E) for subsequent tax years.
The property will retain the same characteristics it had when it was being held by the LLC (defaulting to a partnership) just prior to the transfer. You may have to use Forms Mode in TurboTax Business in order to get this transfer entered properly.
Finally, YES, you should absolutely seek guidance from a local tax professional and/or legal counsel.
