Processing payroll in future year

SUGGESTED

I have a client that will need to process payroll in 2021 before they close 2020.  I've tested this in PR 2.20.2.0 and it allows me to post the payroll but the Aatrix W2 for 2021 says there is no data. The 2020 W2 is correct as are the reports that I verified.  Does anyone have any insight on this?
