According to the majority of fuqahā (jurists), the time for tarāwīḥ remains from ishā until subh sādiq (true dawn).
It is sunnah to perform tarāwīḥ before witr. If tarāwīḥ is performed after witr, then the authoritative opinion of the Ḥanafī’s is that tarāwīḥ will still be valid.
If tarāwīḥ is not performed before sunrise, it’s time period ends, and it cannot be made up for.
It is not necessary to perform tarāwīḥ immediately after the ishā ṣalāh; rather, it can be performed during any portion of the night.
