Turnover not shown in GSTR 3B of March 2018

Turnover of Rs. 10,00,000 was omitted from GSTR 3B for the month of March 2018(2017-18). Now that the turnover has been shown in GSTR1 of the corresponding month but the amount of tax on the said amount remains unutilised in the electronic cash ledger. Now the question is, should that turnover be shown in GSTR3B of May 2018 (2018-19) or should we wait for annual return?
If yes as per the former, the tax has been deposited as per the working of March 2018, but now if that turnover is shown in May's 3B, the output tax ledgers (CGST and SGST) have been changed due to the input IGST component, so in this case, additional SGST would be deposited and some amount of CGST would remain unutilised in cash ledger. This one is unfair as per the point of view of the taxpayer.
The second possibility is to wait for Annual Return. If we show the said turnover and liability in Annual Return , the department would ask for interest on the tax amount as the tax was deposited but not discharged from Electronic cash ledger.
What should be the best possible solution in this case ?
