Please note the VAT Returns form I had posted above, it has all the details of how the tax return report should be.
As @Brucanna mentioned, the reporting for state wise tax is only for revenue sharing purposes, but the tax remittance is not state wise it is central and zero rated supplies has to be one complete sales figure. In the images I posted, for Outputs (VAT Collections) Standard rated supplies or 5% supplies need to be seperated in rows (1a - 1g for 7 different states), but Zero rated supplies need to given as a total value in row 3.
Reverse charged VAT will not be paid, but the amount has to be accounted for and calculated and shown in both Input and Output calculations, row 2 and row 10.
Sorry just reattaching the relevant screenshots here again for reference.
