After you file

I got my 1040NR form using Glacier Tax software. Now when I will send IRS the forms here are the list of forms which I am sending - 1) 1040X 2) 1040NR 3) 8843 4) attached copies of w2 forms. Do I need to include also send my 1040 form too which I got from Turbotax? Also in the 1040x form there is a option called "Amended return filing status. You must check one box even if you are not changing your filing status." For me it is single, I assume I need to fill that right? For the 1040NR form, I need to write "amended" on the top of 1st page right or do I need to write it on every page?For the reason if I write " Mistakenly filled 1040 and received refund. Now submitting the amended one." Is it correct? Thanks in advance.
