Can I file an amended 1040 return for 2021 when the pdf of the 8990 was not attached?
Since Intuit does not have Form 8990 for the 1040, I had to fill it out manually and then I made a pdf of it and accidentally didn't attach it to the return when I electronically filed it. Can I file an amended return with the 8990 attached? I keep reading that the "election" must be timely filed but can't understand what they are talking about in the instructions.
