Itr filed before uploading 3cd

No brother not at all. to be revised, just file tax audit report and complete the formality......because both are independent of one another...so no harm....

But you had to provide the "Date of upload of audit report" in ITR ((apart from the date of audit report))

Its okey if you filed the ITR with a future date as "Date of upload of Audit report" and you uploaded the 3CB.3CD accordingly...

otherwise, I would be good if you revise and rectify the same in ITR

Dontworry, Guess there's no probs though you've already completed the procedures... :-)
