15 February 2021 I was revising Q1(2020-21) TDS return by adding new challan and Deductees, when I was uploading the FUV file on IT portal it was asking for Original RRR no. and Previous RRR no.
i wrote the same token no. in both but when i hv checked in view filed TDS it was rejected by showing incorrect Previous RRR no.. Then i hv uploaded again by writing Q4 (2019-20) token no. but it again got rejected for the same reason. Then i hv wrote Q3(2020-21) token no. it again got rejected for the same reason
I am confused now what is Previous RRR no. ?
