The plan should not have issued a 2018 Form 1099-R for the same money. If they chose to treat this as a 2018 distribution instead of a 2017 distribution, they must issue a corrected code G 2017 Form 1099-R showing $0 distributed. Otherwise they should treat this as a 2017 distribution and issue a corrected code G 2018 Form 1099-R showing $0 distributed.
Only the amount actually rolled over will appear as a rollover contribution on the IRA's 2018 Form 5498. Say the amount was $10,000. With Forms 1099-R showing a combined $20,000 distributed from the qualified retirement plan but only $10,000 reaching the IRA, the IRS is likely to question what you did with the other $10,000. That's why one or the other of the code G Forms 1099-R has to be corrected to show $0 distributed.
