After you file

@pinky_baby36 The IRS specifically requested certain information from you and gave you a fax number to use for it.  That is not the normal way that "anyone" can file an amended return--- so to keep the record straight here for other users who might read this-----an amended return is prepared on a Form 1040X.  As of late August 2020 the IRS will  allow e-filing for 2019 returns that have been amended.  Any other year that is amended still must be printed, signed and mailed.  Unless you are given special permission and a fax number by the IRS you cannot fax stuff to the IRS.
