What is the benefit of reciting Surat Taha three times after Maghrib prayer for eleven days?

Reciting the Holy Quran is one of the best deeds, and its benefits are immense; it is a light and a healing. The reciter receives a great reward: ten good deeds for every letter. The recitation of Surat Taha, like other surahs of the Quran, carries great reward. However, it should not be specified for a particular time, such as after Maghrib, or a specific number of times, such as three times, because there is no evidence for that. All of that is considered innovation (bid‘ah).
