Past Turnover to Show in Offline Tool

Everytime when we upload our GSTR1 Details in the offline tool. It asks us about our Apr to Jul 2017 Turnover and Past Financial Turnover April to July 2017 figures are understood Past Financial Year, what should we type? The FY which was before GST or now FY 17-18, or 18-19?Even now, I have been since beginning, showing the same turnover which I have been showing during my first GST Return in the Past Turnover. Is that ok?
