What I did with this is added the 1099 r so I would be taxed the excess in 2018. I get an e-file error as noted below on the summary w2 sheets only. Just override the numbers so you do not have the over amount. This clears the error. These sheets are just summary sheets and do not get e-filed. The w2 stays the same as originally input with the over contribution which is part of the E-file.
