TDS on SCSS not shown in form 26AS

I hold 2 saving bnk accounts in ICICI bank (my wife is joint holder in both accounts). We, I and my wife have invested in Senior Citizen saving scheme (SCSS) through our bank with respective PAN numbers. We did not have in FY2020-21 much income from fixed deposits which call for TDS deduction. But TDS is being deducted from interest from SCSS in both the banks. Since there was no TDS other than interest on SCSS, bans did not issue any form 16A, TDS certificate etc. Therefore our form 26AS do not show any entry (all entries are zero). Therefore I am not able to fill our Income Tax return (I will not get refund as no TDS is appearing in form 26AS. My question is is not the responsibility of the bank to issue the form 16A indicating the anount paid and the tax deducted?
