can't e-file my returns

I have e-filed the last 6-7 years with no problem. This year I have a 1099-R and a SSA-1099 that I never had before. I suspect it's because of the 1099-R. A message came up that said make sure i attach a copy of the 1099-R. Is there a way to attach it electronically? I also when filling out that part of the return it said to download the information from the institution I used. I clicked on that and it said my tax forms aren't available yet although I printed out my 1099-R from their site last Saturday.
