I downloaded my info QB to Turbo Tax. In QB the income is Uncategorized Income. Do I need to enter all the 1099's in Turbo Tax and that be a double entry as income?

You do not have to re-enter your 1099s if you are using QB.  You can use your income from QB.  Why were your numbers different?  Over/under?  IN my case, my 1099 was higher because the payer recorded monies they did not deliver to my until January 2017 as income for 2016.  QB is my ACTUAL income for the year.
