I have been searching for profiles for PETG & TPU for the A1, and haven’t had any luck really…
Over on printables website there is a user that has posted tons of custom profiles for PETG & TPU, but for the X1C…
Does anyone know of something like that for the A1?
Honestly, until now, I had no problems while using Bambu Lab’s generic profiles, so feel free to try that first.
Keep in mind: PLA might forgive you for not drying it out every now and then, but TPU started crackling like i was frying something in a pan.
I used transparent eSUN TPU 95A with the generic TPU profile and Elegoo PLA/PLA+/PLA Matte/PETG each with their BL generic profiles. eSUN PLA too.
It worked out like a breeze.
If you are looking for special profiles like “best transparent TPU profile” search on Makerworld.
Example: Perfect TPU printing Profile
Bambu Lab also has some interesting posts on how to get the best PETG transparent settings and so on.
Have a good one 
I am the same as @Plastik_Poet.
I do use the eSun profiles Bambu provides and generic for everything else.
I have a high-flow TPU and I use the BL HF profile which works great.
