My spouse and I filed a joint, married return, which was accepted. We now want to file an AMENDED return for 2021, changing to married, filing separately. I understand we have a limited amount of time to do this (until April 18). We want to file the amended return as quickly as possible, but Turbotax indicates this option will only become available "later" in the year.... How LATE will this option become available?? Obviously it will be no use to us if Turbotax delays this option for much longer and it gets to be April 18 or later.
