The only time you enter the property and/or any other assets in the assets/depreciation section, is in the tax year that property and/or asset is first placed "in service" as rental property or rental property asset. You do not enter the same asset each year.
After you enter the property that first year, it will be "automatically" imported into the turbotax program in the next year *IF* you use the same exact account that you used the previous year, to prepare the previous year tax return. This is a "MUST" in order to import anything from the prior year's tax return.
If using the CD version of the program, then the prior year tax file (will have a .tax2019 filename extension) must be in the documents/turbotax directory of the computer you installed TurboTax 2020 on. Then the CD version of the 2020 program will automatically import last year's data from that .tax2019 file.
