You cannot file a 2024 extension request. That had to be done on or before April 15, 2025.
If the 2024 tax return will have a tax refund, there is no reason to file for an extension. The refund will be paid if the 2024 tax return is filed at any time on or before April 15, 2028.
If the 2023 tax return has taxes owed, you should file the return as soon as possible and pay the taxes owed, since penalties and interest will continue to accrue until the tax return has been filed and the taxes paid.
