Can ITC of FY 2017-18 n 2018-19 be availed or not

This discussion addresses whether Input Tax Credit (ITC) for the financial years 2017-18 and 2018-19 can still be claimed. While GSTR-3B filings were permitted with capped late fees until January 2020, it appears that ITC for the period of July 2017 to March 2019 cannot be availed as the return filing dates were not extended, only late fees were waived or capped. The user is seeking clarification on whether further notifications might allow claiming this ITC and what the implications are for interest and penalties.
