I'm not a tax professional, but my research leads me to believe that real estate is a form of capital investment. Just like stock dividends and bank interest, rental income is a form of investment income. As you may have expenses related to operating your rental property, these are considered investment expenses and are used to offset your investment income, potentially creating an investment loss in a particular year. There is a rolling value called your cumulative net investment loss (CNIL) which gets updated each year. At some point your CNIL will be used to adjust your capital gains deduction. When you eventually sell your rental property, your capital gains deduction will be applied to your lifetime capital gains exemption. Your lifetime capital gains exemption will be used to determine how much capital gains tax you will pay on the difference between what you paid to purchase your rental property and what you will be selling it for. So TurboTax helps you and the CRA to keep track of your ongoing investment income losses and that is why your capital gains forms are temporarily locked until the CRA gives the green light, predicted by the CRA to be before the end of March. My own forms are locked because I have reported bank interest to TurboTax in every year since 2017, when I started consistently using this product each year.
