ITR 4 - turnover

which turnover is to be considered while filing return

a) taxable turnover

b) taxable turnover including cgst and sgst

please clarify

for eg
taxable turnover = 500,000
cgst = 40,000 sgst = 40,000

total = 580,000

so, what is the turnover I should mention in return

500,000 or 580,000??? while filing ITR 4 and u/s . 44AD
