US Immigration from Hong Kong

So we ve got our interview date for next Monday. We were only notified on Tuesday. And I m trying to pay the 265 fianc visa fee via ustraveldocs account. Now it kept popping up saying that I have to double check whether my ds160 barcode matches the information and numbers on this ustraveldoc account, the problem is there s no page where I can double check that on my account?! I tried clicking update profile but it doesn t show anything related to confirmation number or ds160 barcode. It also said if I paid my fee and they don t match I may be denied and will not be able to attend the interview. Now I m panicking about that because I had a ds160 form for travel b2 visa from way back in 2015 and I m scared that this account didn t update the ds160. It s also been so long since I ve completed the ds160, I don t remember if I had created any other ds160 but never completed it.

so my question is, do I create a completely new ustraveldoc account? (Which on the site it says don t do that)

or pay the fees and hope for the best?

The worst part is it s a 4 days holiday here this week so I can not contact the us embassy at all until next Monday which is my interview day.

much thanks for anyone that can help or offer any advice!!
