H1b drop off - DS 160

Hello,

I am trying to book a visa slot for H1b drop off in dec 3rd week, i submitted my ds160 and paid the visa after filling ds160 code details in the new website , after successful payment able to see the schedule appointment option. I realized I may have forgot to mention few details in ds160 and i would like edit it out, looks like i cant and probably have to create a new one but I was wondering if i have to pay again incase i start a new application filling in with new ds160 code. what are my options? can i create a new ds160 and printout separately ,leave out the current application as is and send it with all the other documents as a new corrected one. instead of messing up with my existing application…
