Have any option to add B2B invoices of earlier month

I have two B2B invoices in September 17 . That bills weren't added in the returns of that month but the total amount mentioned in the September return as B2C others includes that B2B invoices amounts.

Can I correct that in the December return ?.
If possible , how can I do that ?.

Please give me a solution

Thanks & Regards
