Just reopened my tax return to finish and send in and same thing happened. Got "critical" need to update message. Couldn't open until ran update. My info transferred from 2017 return still intact but 16 hours of info inputted in April gone. Searched computer everywhere for intact file but none. Updated main disk only, but it located my personal file plus back up and wiped out both. Yikes, leaving on trip and no time to redo before due Oct. 15. (Using TurboTax Home & Biz CD copied on to a Mac.)
