Retirement tax questions

i filed yesterday and have a mail in because box 1 is zero.  i printed but have not sent. i forgot to enter my ssa-1099.  my fed refund is zero.  i did not exceed the earning limit that applys to ssa.  i need to get back into my filing with turbo tax to add this 1099 or...can i send a copy of this ssa-1099 when i mail in the printed copy???
