My return keeps getting rejected. It is an amended return and I don't see where to address that Reject Code R0000-932-02

How to submit an Amended Return

[Critter-3]

It is too late to efile any 2020 return so all you can do is print, ink sign and mail it in.

That code means that someone already submitted a return electronically with the same SSN that you used.  Make sure the SSN is correct on your return, then print and mail it in.  The IRS will sort it out, but it will take some time.
