If the loan repayments stopped when you separated from service, I would expect that this distribution would be an offset distribution. If so, this would be indicated by the inclusion of code M in box 7 of the Form 1099-R. Code M means that you have until the due date of your 2021 tax return, including extensions, to come up with the funds to roll the money over to another qualified retirement account such as an IRA, allowing you to continue to defer this income and avoid any potential early-distribution penalty.
This does not qualify as a Coronavirus-Related Distribution because the deadline for obtaining a CRD was December 30, 2020. (This distribution occurred after that deadline; the loan itself was not a distribution.)
