US Immigration from Jordan

hello , so when i am filing the 160 ds form do i have to list all social media accounts even tho i don't really use them like i do have one but i don't use

When is your pd ?

So i need to fill the 160 ds form for my k1 visa to schedule an interview then i have to go to this website to log in and make an appointment from there
what i want to ask is , does anyone has a video that teaches you the steps 1 by one and what do i need to have first before filling the 160 ds form
do i have to wait the embassy to contact me first ? or can i do it right now since my visa says ready on the https://ceac.state.gov/CEACStatTracker/Status.aspx?App=IV
thank you very much in advance.

So i just check my The Nvc site and it said that my application is ready , What next , what do i have to do?
do I have to schedule the interview or they do it ?

I received an email yesterday from the NvC that our petition is being sent to the Embassy. In the email they spelled my fianc s first name wrong. Do I need to have this corrected? Or is it not a big deal since it s just an email
