Helpmeeee Maby because it's 4g lte? Does my phone not support that? Also what do you mean by verify apn settings?...the data still isn't working
The Pixel 5a supports 4G LTE, but it may not support the particular bandwidth that Tracfone uses. One point to consider is that Tracfone's official support page for Google devices only lists the Pixel 6a (link). It's unlikely, but it may be that the 5a is not supported by Tracfone, and if that's the case, that's not a Graphene thing, that's a Tracfone thing. This is something you should verify with Tracfone's support.
For APN settings, you should refer to official Tracfone support for the most correct info, as that is always heavily dependent on each carrier's settings. I found this link, but I have no idea how correct or verifiable this would be.
You can verify this under the APN settings of your phone:
Settings
> Network & internet
> SIMs
> (your Tracfone SIM?) > Access Point Names
