@wland @Pat Thank you for the support! I finally got it working. It was a very similar problem as in the other topic. I have tried so many different setups but it was having them correct all at the same time that was the issue. I now use PotatoFarmers config file for the F9P but with the baudrate of 460800 on both the teensy and the F9P and the connection scheme as shown in my first post.
