Expenses in GST

Dear Sir / Madam,

Though RCM for Sec 9(4) is not applicable until 30th June 2019, For FY 18 - 19, should we need to show the expenses like Rent, Staff welfare, Electricity bill, Printing and Stationery, Labour contractor expenses, Crane Rental charges, Business promotional expenses in GSTR3B?

or

Please confirm is that OK to show the Business Operation information alone in GSTR3B?
