But note: The original "Thullatha Manamum Thullum" was composed by for Tamil film Kadhalan (1994). The Telugu dubbed version of that same film had the song as "Thulli Thulli" with lyrics by Bhuvana Chandra, sung by S. P. Balasubrahmanyam and Swarnalatha.

However, if you are referring to a proper with similar tune and feel, the most accurate answer is:

"Gudilo Chilakamma" Movie: Gangleader (2019) Singer: Shreya Ghoshal, Vijay Prakash Music: Anirudh Ravichander (originally composed for the Tamil song "Thullatha Manamum Thullum" from Kadhalan , but reused/recreated in Telugu)

So if you want the exact Telugu version of the original song, it is from the Telugu dubbed movie Kadhalan (also called Premikudu in some contexts, but careful: Premikudu is the Telugu dub of Bombay — correction: Kadhalan Telugu dub is simply Kadhalan ).

The Telugu remake of the Tamil song (originally from the Tamil film Kadhalan / Humse Hai Muqabala in Hindi) is "Thulli Thulli" from the Telugu film Kadhalan (also released as Humse Hai Muqabala in Hindi), but more commonly recognized in Telugu as a dubbed version rather than a full lyrical remake.
