If you transfer your information from the previous year when you start your tax return, and do that consistently every year, TurboTax will keep track of the capital loss carryover. If you are using TurboTax Online, you have to make sure that you use the exact same user ID every year in order to correctly transfer the information from the previous year. (A lot of people have more than one TurboTax Online account, often without realizing it.) If you miss a year, TurboTax will lose track of the carryover.
