I received a 1099-R with code P for the excess deferral contribution I made in 2017 which was reported in March 2018 but the check was not issued until April 20, 2018. I also received a second 1099-R for this same excess deferral PLUS the earnings and it shows code 8. I put my return on extension so technically I received the return of the contribution before the due date of the return. How do I report this on my 2018 return so I am not being taxed on this money twice??
