Similar situation here. Sent my 1040X the first week of May, been 15 weeks now with no acknowledgement of receipt (https://www.irs.gov/filing/wheres-my-amended-return), and seems they completely disabled call-in contact. Can't tell if it's in their mail trailer or the USPS never delivered (shame on me no return receipt). Just got my first late notice. If they would simply acknowledge receipt that would help a lot, I am tempted to assume it's lost and efile a duplicate. If I could.......
Back to the original question - When will TurboTax upgrade TT Pro 2019 to include 1040X efile?
