Thanks Marilyn. I just cleared the cache/cookies, deleted/re-entered the 1099-R, and this time did have the chance to say that the entire distribution was not taxable in NJ. There were also many more questions about total IRA values, taxed contributions, etc. that were not there before. I'm not sure how they relate to an inherited Roth yet - I need to look at in more detail. In the end, is still says about 25% of it is taxable in NJ but I'll keep at it.
