SBI incorrectly deducted TDS of ~70K as per 194N in FY20-21, after lot of followups and multiple positive/negative entries in 26AS they finally added it in FY22-23 with data of booking of Nov '22 but transaction date is still Jan '21 What's the proper way to get refund for the same?

Should rectify ITR of FY20-21 or I can claim it in this FY's ITR? If I check 'Tax Credit Mismatch' of AY 21-22 It says "Tax Credit Claimed is Fully Matched with Tax Credit available in 26AS".

How to proceed with rectification?

I am retired and was having a FD in syndicate bank. Which merged with Canara bank about 2-3 years back. In FY 21-22 Canara bank deducted TDS @ 10% and I got form 16A. But in FY 22-23 the same bank deducted TDS at 20% and there is no Form 16A.I realised this problem when checking form 26as, AIS ETC.
When I contacted bank about 10 days back they saw that in my account my PAN NO has not been updated. They accepted their software mistake which merged syndicate bank details with Canara bank software. Now they keep saying that our head office is going to rectify it. But last date of ITR filing is one week away and how do I file my ITR. What other action I can take towards bank.
