Are you using the online or desktop version? Check every T5008 slip entry to ensure that each transaction has a valid disposition date within the 2024 calendar year. Ensure that the date entered is in the correct format. Date of Disposition (dd/mm/yyyy).

I also recommend deleting the slips and reentering them. If you are using a desktop version, make sure it's up to date.

Thank you for choosing TurboTax.
