You can e-file your return and the 1099R's do NOT need to get sent to IRS (as the issuer of the 1099R's sends the IRS a copy of them).
So your return filed will be 100% paperless (unless you have a very unusual situation and we will alert you if something needs to be mailed to IRS).
Now if you do not e-file and paper file the tax return, then the 1099R's and any other documents that have Federal taxes withheld would be mailed with the return to IRS.
