I need to file a corrected form 1099 for a sub contractor; how do I do that?

Answered in your new post of the question.

I need assistance in filing a corrected 1099-NEC   The business EIN is incorrect

You will need to download form 1099-NEC from IRS.gov and make your corrections by hand.  Quick Employer Forms does not support corrected forms at this time.

Please see IRS: Form  1099-NEC and Instructions.  Be sure to check the "corrected" box on the 1099-NEC.
