I keep getting rejects when I try to e-file a 2020 amended return that the taxpayer e-filed on another tax platform.. It does not recognize the 1040 X present in the e-file package. I have been through at least three pro series tech assistance sessions to no avail. When I try to e-file from within the tax return, it states the federal amended return is not ready because the federal return itself has not been completed. I would appreciate any help.
