Unclaimed ITC

Generally the time limit for obtaining credit is due date of filing return for the month of September of succeeding financial year or date of filing of annual return, whichever is earlier. For your query though date of filing annual return is yet to pass by due date for filing return of September month of 2018 has already gone. Hence I guess it's not possible to take such credit now.

No... ITC not available for the above said query...

If the taxpayer is from Gujarat then it can take the credit for the F.Y. 2017-18...as per HC new judgement. Otherwise as per sec. 16(4) it can't take the credit for the F.Y. 2017-18.
Further credit is to be taken in GSTR-3B for the month of June or July. And, it is to be shown in GSTR-9 in table 8 as well as table 13 even though the table asked for credit taken in F.Y. 2018-19 and taken in F.Y. 2019-20.

yes, we can claim the unavailed ITC of F.Y 2017-18 GSTR 2A in GSTR 3B upto filing march 2019, If any unclaimed ITC pertaining to the FY 2017-18 is not availed, then I will lapse while filing GSTR 9 OF FY 2017-18.

good clarification and information
