How to tell them apart
Both express an uncontrollable feeling or sensation, but てたまらない leans toward the speaker's own visceral reaction that he or she empathises with, while て仕方がない stresses that the feeling is beyond control because of some external cause. Swapping them is usually fine for personal states like 暑くてたまらない and 暑くて仕方がない, but て仕方がない is the safer choice when you want to emphasise that a situation forces the feeling on you, as in 飛行機の音がうるさくて仕方がない.
- 堪らない・たまらない Use てたまらない for your own or an empathised person's unbearable feeling or strong desire.
- て仕方がない Use て仕方がない when an external cause makes a feeling or sensation impossible to control.

堪らない・たまらない ranai tamaranai
Unable to endure; overwhelmingly intense
たまらない expresses that a feeling or desire is so strong it is unbearable. It attaches to the te-form of a verb or adjective, typically with て before it, as in たくてたまらない. The examples all show it following the て-form of a wanting expression, and it is used in everyday spoken Japanese.

て仕方がない te ganai
Unable to resist doing or feeling something; to an extreme degree
て仕方がない attaches to the て-form of a verb or i-adjective and expresses that a feeling or urge is so strong the speaker cannot help it. It typically follows desire or emotion words like 飲みたい, 逢いたい, or うるさい, and is used for the speaker's own uncontrollable feelings.
