Can pending ITC of FY2019-20 be taken in Current Year's GST-3B?

Dear friends,

ITC totalling to Rs.20 lacs was not taken by me in GST-3B during the FY 2019-20 but was considered in Income Tax return for the year ended 31st March 2020.

Can I now claim this set off in Current Year's GST-3B in the month of January 2021?

Thanks
