Do I have to submit estimated taxes if I already had extra withholding on my W-4?

Hi, 

I have a regular job (W-4) and I am also working as an independent consultant.

In order to avoid penalties I selected "Extra Witholding" on my regular's job W-4 which I believe covers all the taxes owed on my independent consulting job.

Do I still have to file a Form 1040ES 1?

 

If yes, did the timeline for the first quarter was also pushed out due to Covid-19?

 

Thank you and best regards,
