Per @MonikaK1 Expert - she posted yesterday "I've been advised today by management that the work on the depreciation section of TurboTax is continuing and expected to be completed with an update coming the evening of Thursday, February 19th."
There are many many threads regarding this ongoing issue for weeks under several different categories in the Community. Many of us are extremely frustrated with Turbo Tax - it's absolutely unacceptable that this section has been unavailable since I purchase the Desktop Premier back in December. H and R Block and other tax providers have all had their depreciation sections available.
