Apart from singing songs for films, Mohan performed alongside Mohit Chauhan in a music video of the TV show Yeh Hai Aashiqui and the duo was featured in some of the episodes in the series as musical narrators. She was also part of the music reality show The Voice India Kids as one of the mentors, along with Shaan and Shekhar Ravjiani. In the year end, she served as a coach in the second season of the Indian reality talent show The Voice. In 2017, Mohan recorded "Khoobsurat Star Parivaar" alongside Jubin Nautiyal. She also performed two songs for the web series titled "Mixtape" produced by music label T-Series. The fusion of "Dua" from Shangai and "Saware" from Phantom, performed along with Salim Merchant was received positively among critics. In spite of featuring in the single "Man Marziyan" she was heard in several tracks recorded for films. She was heard in an upbeat composition by Rahman, along with Arjun Chandy and Savithri R Prithvi for the soundtrack album Ok Jaanu. Titled "Jee Lein", it received mixed reviews from critics. She was next heard in the Chirantan Bhatt's composed romantic track "Bawra Mann" performed with Nautiyal.

Mohan collaborated with Pritam and Rochak Kohli for two albums; Jab Harry Met Sejal and Lucknow Central respectively, where she performed the song "Raula" with Diljit Dosanjh for the former. Additionally, she contributed to the music album of Baadshaho by performing a retro-contemporary fused item song "Piya More" with Mika Singh for an Ankit Tiwari-composition and also by recording the recreated version of "Keh Doon Tumhe" from Deewaar (1975). Titled "Socha Hai", it was removed from the film due to problems with music rights while "Piya More" was also altered slightly due to the legalities, since it does sounds "similar to what Tiwari has palmed off to another producer". In 2017 December, she voiced both speaking and singing parts of Rapunzel in the Hindi dub of Tangled: Before Ever After. In 2019 January, she sung for the series T-series Electrofolk where she was seen alongside Payal Dev performing the track "Aaoge jab". January 2019, Mohan released her single "Kithe
