accidental Touchwiz home uninstall

I had my note 5 for a long time now. After having it for some months I decided to root my phone. Every thing went well then I started to uninstall system apps like Power point, Word, samsung email and s voice but I clicked on touchwiz home therefore uninstalling it. I tried getting apks but they all say the samething "The Package conflicts with an exiting package by the same name" I checked in all apps and in file explorer to see if there was a package named the same but did not find it. I have also tried factory reset it did not work.
