That's what I am hoping occurs. I am also hoping any PDF support would be sent in as well. 

I agree it seems likely Lacerte would function this way. I was just wondering if there was any official Lacerte guidance noting this is the case.

Lacerte, like other similar professional tax products, has been determined by the IRS to meet the MeF Schema and will transmit whatever the IRS requires for e-filed 1040X.  What it sends is transparent to you and should be the least of your worries.  Intuit moderators had previously confirmed that much in this Community.

In case something needs to be manually attached, you should expect to be prompted by the diagnostic.  If there's any attachment you would like to submit with the 1040X, you should follow the same process to attach it as a PDF, like you do with the original return.

As Susan says, the IRS has always required only forms and schedules that are changed.
