Geek Squad did a purge and reinstalled my data but not software

I recently had a clean up of my iMac hard drive at the Geek Squad. I have had Quicken installed on here for many years (three versions of quicken at least). My most recent I believe was 2017 upgrade. I have downloaded the 2016 version but I cannot figure out how to enter my data into the Quicken program. Can any one help or suggest who I should call? Geek Squad? Quicken? Apple? I've tried, but I'm not an expert. I just want to be able to use my Quicken for my household accounts. Thank you.
