I am trying to get the table centered and all the columns but so far getting this table as the output 
Any suggestions how have the longtable centered and have all the columns?

You can use introduce linebreaks in the column heads with the makecellapckage and reduce the value of tabcolsep, in order to reduce the table width. I took the opportunity to add some æsthetic improvements:
documentclass{article}
usepackage{longtable}
usepackage{makecell}
usepackage{array}
newcolumntype{C}[1]{>{centeringarraybackslash}m{#1}}
usepackage{caption}
begin{document}
renewcommand{theadfont}{normalsize}
setlength{tabcolsep}{4pt}
setlength{extrarowheight}{2pt}
centering
begin{longtable}{|l|l|l|l|l|l|}

Correct answer by Bernard on May 29, 2021
Probably you also like this alternative layout based on tabular*, booktabs and siunitx. If you reduce the font size to small, the whole table fits into the textblock of a standart article:
documentclass{article}
usepackage{makecell}
usepackage{booktabs}
usepackage{siunitx}
sisetup{range-phrase=,--,}
renewcommand{defaultaddspace}{3pt}
usepackage{caption}
begin{document}
begin{table}
renewcommand{theadfont}{normalsize}
centering
small
setlength{tabcolsep}{0pt}
caption {Covid-19 Test Results by Demographics} label{tab:title}
begin{tabular*}{textwidth}{@{hspace{6pt}}l@{extracolsep{fill}}
S[table-format=2]
S[table-format=1.1,input-symbols = {()},table-space-text-pre=(, table-space-text-post=%),table-align-text-post=false]@{;}
