I have read a lot of prior posts with no help.  I am trying to efile 2021 amended return.  I efiled original return.  I have followed instructions and have saved original return under new name.  Am working with original return, not the one I just renamed.  Have checked the boxes to efile amended federal and nys.  Both 1040x and ny it-201x are good.  When I go to efile from efile center, the amended returns are listed but are greyed out so can’t select for efiling.  Any suggestions?
