221G for social media veting

I have a query and would appreciate guidance if someone can help.

In my DS-160 form, for the social media section, I entered my username/identifier as my email address, since the form says: “In the space next to the platform name, enter the username or handle you have used on that platform.”

I listed Instagram, LinkedIn, and Facebook, but later realized that my profiles are not searchable using my email address.

My question is:

  1. Should I submit a new DS-160 with the correct social media handles?

  2. If yes, is it acceptable to carry the new DS-160 confirmation to the consular interview, considering that my biometrics were already completed in Chennai on Dec 9?

Any advice or similar experiences would be really helpful.

Thank you.
