ITC carry forward of Previous Year

Dear Team,

ITC for the FY2019-20 which was showing in GST-2A was not considered by me in the 3B return.
However, i took the ITC set off in the following year's GST-3B return i.e. 2020-21.

Now at the time of filing the GST-9 Annual Return, the ITC pertaining to the FY2019-20 is showing as difference. So what is to be done?
Under which column am I supposed to show this amount? Would I have to pay the amount?

Please help. Thanks.
