I would not worry about the imports - it might be that a 1099-R with a code R is not reverent to a 2016 tax return.
A 2016 1099-R with a code "R" does not make any entries whatsoever on either a 2016 tax return or an amended 2015 tax return. It's only purpose is for the financial institution to notify the IRS of the recharacterization. The only proper was to report the recharacterization on your 2015 tax return is how you did it - in the IRA contribution sections and an attached line 15a explanations statement.
Entering it into 2016 with a code R will just tell you that you need to amend 2015, but does not offer any directions as to how to report it - just entering the same 1099-R into 2015 will do nothing.
