Compensation for services that is not W-2 wages should be reported to you on Form 1099-NEC, and such compensation is subject to Self-employment Tax and should usually be reported on Schedule C. Reporting on 1099-Misc is incorrect if the payments were the result of work you performed. You may want to contact Company A, but it appears that learned the error of their ways and determined that they should issue 1099-NEC, not 1099-Misc.
