C as pital gains tax reporting

How do you report Capital Gains for the sale of a property this month if you have already completed last years self assessment tax return, and the tax return for this year can't be completed until after April 2025. How do you report the gains in order to comply with filing within 60 days of the sale? Is there a stand alone form you can file separately?
