Aatrix on macOS cannot produce a W-2C, the form used to submit corrections to a submitted W-2 form. If you have access to a Windows environment, it is recommend to generate W-2 forms using CDM+ on Windows to allow for future corrections.
If you do not anticipating needing W-2C forms or are comfortable submitting a W-2C you create manually, proceed to create W-2 and W-3 forms on macOS.
