The visa application process cannot be completed until you appear for an interview with a consular officer. You should probably cancel your interview just to make it official.
According to this Quora Q/A web page
You donβt need to delete the form. Just cancel the interview appointment, if you made one. Eventually, if the submission isnβt used, the system will probably delete it. Not showing up will not count as a refusal.
and
You can cancel an interview appointment by signing-in, going to the "My Account" home page, and selecting either the "Cancel Appointment" or "Reschedule Appointment" links.
If you havenβt take any appointment or payment of fees than after 30 days of submission the DS160 form automatically vanishes. It should not affect your current visa.
