FILING AN AMENDED RETURN

[JRYAN4]

Within a day of electronically filing a trust return, I realized that I omitted something and so filed an amended return.  When it came time to filing the amended return, the app told me I had to submit it by mail.  Yet, when I went through the process of printing the amended return, it only printed the Electronic Filing Instructions for the return instead of a cover sheet telling me where to mail the amended return.  Is it possible that my amended return was also sent electronically?
