Annual Information Statement (AIS) issues with 5yr National Savings Certificate (NSC)

In the "Interest from deposit" section of AIS, it shows:

SFT-016(TD),
Interest income (SFT-016) – Term Deposit

ACCOUNT TYPE: Time Deposit
INTEREST AMOUNT: 70,399

AIS is showing the full interest paid on maturity of a 5yr NSC.

Questions:

1) Can NSC be classified as "Term Deposit" ? Is SFT-016(TD) valid in case of NSCs ? Shouldn't it be SFT-016(Others) instead ?

2) The whole interest amount accumulating over the past 5 yrs for the NSC has been shown/reported in one go in the AIS by the POSTMASTER.

As per my understanding, usually, when long term deposits/FDs are opened with banks and are spread over several FYs, the interest accrued in each FY is reported and offered for taxation/TDS/etc.

The NSC in question was for 1,50,000 purchased in FY 16-17, @ 8% pa, Compounded Yearly.

See table:

So, shouldn't only 16,326 for FY 21-22 be reported in AIS instead of the total interest of 70,399 ?

3) Since 70,399 is the reported value which reflects also in the TIS's processed & derived values, should I file for an AIS feedback using the AIS utility with "Information is not fully correct" option and try to correct it to 16,326 ?

4) In the ITRs for previous FYs, yearly interest amounts derived from the table above (12,000, 12,960, 13,997, 15,117) have been shown under "Interest from Deposit(Bank/Post Office/Cooperative Society)" and also as re-investments under 80C for respective FYs.

Unless it's corrected in the AIS and then accepted, in order to reflect in the TIS, auto-fill value in ITR's "Interest from Deposit(Bank/Post Office/Cooperative Society)" for FY 21-22 would be wrong.

And if I report 16,326 instead of 70,399 while filing the ITR, there are chances that a demand would be raised.

What to do ?
