Mismatch of interest in interest certificate and tds certificate

I have 3 fixed deposits. The total interest accrued as per interest certificate issued by bank for FY 2021-22 is 36665 however total interest income as per tds certificate is 40000. I have already filed my ITR disclosing interest income as 36665. Is this a serious issue?? Should I go and enquire in bank?? Please help me
