Carmen tiene que limpiar su dormitorio.
I'm not sure if this is what you're looking for, but I think you're missing the verb "dijeron" after me and before que.
Can you please post the audio?
Answer: 1. caminando en el bosque, 2. voy a descansar
Explanation:
1. The verb needs to become a present participle since it is using estar.
2. The statement says, "I am walking in the forest," so the most reasonable answer would be, "Tomorrow, I am going to rest."
