Set your FIFO or LIFO options online before you place an order.
If broker doesn't have that online option (unlikely), you'd have to write a paper letter to broker with instructions.
The default is FIFO.
If you want to claim a 2024 loss , broker must wait to see if you bought back too soon in 2025. That's why your 2024 1099-B won't come until late February 2025.
