@Destinylwood - we don't know if there are going to be two checks or one check for a married couple.
Further, if it is one check, I suspect the check will be made out to both of you since you filed jointly . if that is the case you BOTH would need to endorse the check to cash it. if one spouse tried to cash it without the other's endorsement on the back of the check, that would be fraud!
if you already filed 2018 or 2019 they already know you filed, so that may be why it was rejected.
Many unknowns here.
