My amended return is zero? I have not received my tax return yet but when I amended it it says zero? Although they told me my irs was not affected . I’m just wondering.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

Why are you amending the 2020 tax return before the federal tax refund was received?

Because I forgot to include my NEC and the deadline was may 17th so I amended it that day.. What will happen now?

If you e-Filed an amendment and it was ACCEPTED, now you just wait.
