Amended 2018 (itemized) with missing 1098
I am amending my 2018 return due to a 1098 that was not sent. I have 2 others that were sent and filed in my return accordingly.
My question is do I need to attach the missing (new) 1098 to the amended return?
Do I need to attach all 3 1098 forms (including the 2 accounted for during filing) ?
